SAP BASIS INTERVIEW QUESTION ANSWER

The purpose of the SAP T000 table is you can view the list of users those are defined in the SAP system.

RFC is the abbreviation of Remote Function Call. This is a type of mechanism which helps in communicating as well as exchanging various types of information across the other SAP systems.

Mainly four types of RFC are present. These are namely,

• Synchronous RFC (S RFC)
• Transactional RFC (T RFC)
• Asynchronous RFC (A RFC)
• Queued RFC (Q RFC)

Transactional RFC allows the processing of the sent request for an error in the system, only once. This is done after allocating an ID for the transaction process which is also known as TID. It is different from asynchronous RFC only in this aspect. The availability of the remote system is not necessary at the present moment in the T RFC.

JSPM is the abbreviation of Java Support Package Manager which is used in order for the application of support packages on the deployed components of the software. Basically, JSPM is an important tool that helps in the installation of the packages and also all the components. To deploy packages, JSPM often uses SDM.

On the other hand, SDM which is the abbreviation form of Software Delivery Manager helps in importing Support Packages of Java. This is also used for deploying software packages and also used to manage them. These packages are said to be received from SAP.

SAP note is used to implement the removal of errors in a single program or a transaction.

The kernel is the one that contains .EXE files which are also known as executable files. The older version of these files gets replaced after Kernel gets upgraded.

Support packages are basically just corrections.

SAP system defines SAP singlet stack system. These can have two types of runtime engines like JAVA or SAP Netweaver as ABAP. An example – Single Stack System (JAA) is basically SAP Enterprise Portal System (Ep). On the other hand, Single Stack System (ABAP) is basically SAP ERP (ECC).

The chief responsibilities of the SAP Basis Administrator are as follows –

• Configuration as well as installation of the system.
• The management of performances of various kinds of components.
• Load server balancing.
• Management of integration and interfaces with servers.
• Managing various kinds of servers and services provided by them.

There are five different types of user systems in the SAP system. These are as follows –

• Dialog user – Mainly for accessing the interactive systems from GUI, this type of server is used.
• Communication User – For external RFC calls, this type of user is used.
• System User – System User mainly helps in the background processing and intra system communication.
• Service User – Anonymous and a large group of users mainly use this type.
• Reference User – Allowance of assignment of extra authorization is done by this user. These are not related to persons as users.

SAP GUI is basically a client tool that helps in accessing the central server and also runs on various operating systems like UNIX, Microsoft Windows, and Mac etc. SAP applications like the SAP Business Intelligence System and SAP ECC are all managed by SAP GUI.

There are mainly three standard clients and these are as follows –

• 000 – This becomes available with the installment of the R/3 system. This is also known as the master client.
• 001 – Basically, 001 is just a copy of 000. It has a test copy. In order to create new clients, this is used.
• 066 – This client is known as the SAP Early watch. If diagnosis and monitoring services are required in the SAP system, this is used.

New client can be created by following these steps –

• The transaction code which is to be used in order to create a new client is SSC4.
• Click on New Entries and put the details like City, Client number and name and Currency and the Roles, etc.
• Data specific to the client needs to be entered and permission must be set.
• Click the save option.

SAP system can be locked or unlocked in two ways –

• Manually or forcefully
• Automatically

For single-user and for multiple users, transaction to be used is SU01 and SU10 respectively.

The conditions must be specified in order for the background job to be started. This is said to trigger the starting of the job. The following are the different kinds of start conditions that are to be used in order for the background job to be started –

• Immediate
• After Job
• Date/Time
• After Event
• At Operation Mode

The categories are as follows –

• Class A – High Priority: This category is mainly used for very critical and urgent tasks. Hence, these tasks also get scheduled with class A priority job. Maybe one or more than that background work process gets reserved by a Class A job.
• Class B – Medium Priority: After the Class, A priority jobs get completed, these types of jobs get executed.
• Class C – Low Priority: After the completion of jobs of classes A and B, the job of class C gets started.

Users who are working the SAP system mainly use SAP GUI for Java or SAP GUI for Windows.

For users who are working as ABAP developers, SAP GUI for Windows is used.

• When the operating systems of the users are not Microsoft, SAP GUI for HTML and SAP GUI for Java are mainly used. However, they can also use SAP GUI for windows.
• For the integration of Dynpro transactions to the Portal, mainly SAP GUI for HTML is used. Dynpro-based applications are well integrated with the help of this, into the portal.

Instances in the SAP system get created when the system gets installed and configured. Processors, memory, and other resources get referred to by these instances. Various sources can be shared by users after logging in to the system. This is also allowed by the SAP instances. These are managed by CCMS. Users use them to log in to the SAP system. One or even more than one instance can be present in the SAP system. Using only one CCMS, only one instance can be set up in the system. Two or more of those instances can be used to configure the system.

Data sharing across the SAP system is not available in the private mode as these data are allocated to specific users exclusively. Due to the exhaustion of the extended memory, this type of mode occurs.

When all the other users are online, the SAP patches can’t be installed. This is because these patches will not be able to be updated and terminated by the support manager. Hence, the best time to install SAP patches is when there is an absence of users’ login in the SAP system.

The object directory entries are included in the table TADIR.

The list of repaired objects gets stored in the system including ADIRACCESS keys.

Parameter Tab cab is used to allow access to the T-code which is assigned to the users to work on.

Personalization Tab can be used to connect RFC across the various systems.

In service users, passwords are not checked as the rights over the passwords are only entitled to the admin. Users can’t make changes to the passwords. Anonymous users use service users. Multiple logins are also possible.

GUI login is not possible for the reference user. User authorization from one user to another is made possible by this during an emergency.

Logon groups are mainly defined with the help of Tcodesmlg. At first, the group needs to be created and then the instances are to be assigned for those groups.

SAP installer that is SAPinst.exe is to be employed in order to use or install JAVA patches. These patches can be deployed with the help of JSPM or also known as Java Support Package Manager and SDM or also known as Software Delivery Manager.

Data transfer can be successfully conducted with the help of using BDC. There are three functional modules namely,

• BDC_OPEN_GROUP: In this module, mainly the client and sessions as well as the user names get defines specifically.
• BDC_INSERT: Data can be inserted from one session to another with the help of this module.
• BDC_CLOSE_GROUP: Mainly used for closing the batch input session.

Client refresh mainly includes copying or overwriting to an existing client. However, if the newly developed client gets copied, this is called client copy.

The full form of business KPIs is Key Performance Indicators. The performance of a company gets indicated strategically with the help of KPIs. The performances of the company get compared with the growth of the company. In this way, KPIs help in leading the company by keeping a good track. It also helps in doing a comparison between various market leaders.

The SAP system gets installed with German and English as the default language. Supplementary language gets installed in order to get other languages.

SAP basis acts as an operating system or a platform for SAP applications to run. It supports the entire range of SAP applications.

• System Trace: When you want to record internal SAP system activities, system trace is used. The trace is useful in diagnosis internal problems within SAP system and the host system.
• System Log : To know the recent logs for application server and CI, System log is referred.
• Developer Trace: In the event of problems, developer trace, records the technical information about the error or problem

For problem analysis and system monitoring Developer trace or System log is used.

• Check the Database status
• SAP services
• SAP management console ( Dispatcher, IGS and Message Server)
• You need to find out trace root on the basis of point at serial no ( c ).
• Check network connectivity if everything is ok

In private mode, the heap data is exclusively allocated by the user and is no more shared or available across the system. This occurs when your extended memory is exhausted.

Two users “OPS$adm” and “OPS$SAP” Service are created in your SAP system and to connect and communicate with database internally this user mechanism is used.

RFC (Remote Function Call) is a mechanism to communicate and exchanging the information between other SAP systems. There are four types of RFC’s system

• Synchronous RFC ( S RFC)
• Asynchronous RFC (A RFC)
• Transactional RFC ( T RFC)
• Queued RFC (Q RFC)

Transactional RFC ( T RFC ) : This type of RFC is similar to asynchronous RFC, but by allocating a transaction ID (TID) it makes sure that the request sent multiple times due to an error must process only for once. In T RFC the remote system does not have to be available at the moment unlike asynchronous RFC.

OCM stands for online correction system, by using SPAM you can apply OCM Patches.

To export or import tables in SAP from OS level you have to follow three steps and by using R3trans utility in SAP

Step 1: Collect all list of tables to be exported

Step 2: Check whether enough disk space is available in the directory where you going to export.

Step 3: Create two control files for R3trans which will be used for import and export.

SAP Note: An error in a single transaction or program is removed by implementing a SAP note.

Kernel: Kernel contains the executable files (.EXE) like other applications and when a Kernel upgrade is done a new version of the EXE file replaces the older versions.

Support Package: SAP support packages is a bunch of corrections, this can be used by applying transaction SPAM

The list of objects that have been repaired can be found in the system having ADIRACCESS keys.

Table TADIR contains object directory entries.

When other users are online we can’t install SAP patches, as support manager will not be able to update and it will terminate it. So it is always feasible to better apply support packs when there is no users login into the system.

JSPM ( Java Support Package Manager) is used to apply support packages on deployed software components. In other words it’s a tool that allows you to install the components and support packages.

SDM ( Software Delivery Manager) is used for importing Java Support Packages. To deploy and manage software packages received from SAP, SDM tool is used.

To disable import all option from STMS in SAP, steps are:

• Go to STMS T-code
• Go to menu option overview
• Select System
• Choose SAP System
• Go to transport tool tab
• Create parameter “No_Import_All” with value set as 1
• Save it

Parameter Tab: It will allow access to assign T-code on which one has to work

Personalization Tab: It is required for RFC connection between systems other than user personal information

Different types of users in SAP are

• Dialog Users
• System Users
• Communication Users
• Service Users
• Reference Users

• Service User: For “service user” initial password or expiration of password are not checked. Only admin has rights to change the password, users cannot. Multiple logins are possible.
• Usage: Service users are for anonymous users. Minimum authorization should be given to such type of users
• Reference User: For this kind of users GUI login is not possible.
• Usage: In case of emergency, with the help of reference user, it is possible to provide one user authorization to another user.

To restrict multiple logins you have to set the parameter as

Parameter should set in RZ10

a) login/multi_login_users= set to 1 to activate (If this parameter is set to value 1, multiple dialog logons to the R/3 system are blocked)

b) login/disable_multi_gui_login= List out the users that should be allow to logon for multiple times

While writing the user ID’s things to be taken care are, list the user IDs separated by commas “..” , between user IDs do not leave space characters and to see the changes restart the R/3 instance.

To change the number of work process at the OS level, you can increase the no. of work processes by modifying the parameter rdisp/wp_no_=

Status of a WP at OS level can be checked by executing dpmon.

Logon groups can be defined using the Tcode smlg. In order to do that you have to create the group and then assign the instances for that particular group.

A single stack system is defined by SAP system either with JAVA as runtime engine or SAP Netweaver as ABAP.

Eg: Single Stack System (Java) is SAP Enterprise Portal System (Ep)
Single Stack System (ABAP) is SAP ERP (ECC)

To use the JAVA patches , SAP installer (SAPinst.exe) is employed. SDM and JSPM are the latest versions of tools used to deploy Java Patches.

To solve queries which cannot be solved by using the method interfaces, a set of information is used. This set of information is known as “ Data Sets”.

To check the system logs of SAP application at OS level, SAPMMC -> SAP systems -> SID -> SysLog

A list of steps among t-code in known as logical LUW

Homogenous system copy= Same OS + Same Database

Heterogeneous system copy= Different OS + Different database or same database

Using BDC programming a data can be transferred successfully. There are 3 functional modules which can be used in a sequence.

BDC _OPEN_GROUP: Name of the client, sessions and user name are specified in these functional modules.
BDC_INSERT: It is used to insert the data for one transaction into a session.
BDC_CLOSE_GROUP: It is used to close the batch input session.

An “OK” code is used by a program to execute a function for example after a push button has been clicked.

Transaction code or “t-code” is a “shortcut” that helps a user to run a program.

Client refresh is overwriting or copying to existing client, while copying the newly created client is called client copy.

To check the schedule background jobs and to execute them parameters like rdisp/btctime is used. These parameters define background processing batch scheduler.

SAP Internet Demonstration and Evaluation System or SAP IDES, this system demonstrate the functionality of various SAP solutions used by important customers.

The purpose of TDEVC contains development classes and packages.

There are seven types of work processes they are:

• Dialog
• Enque
• Update
• Background
• Spool
• Message
• Server
• Gateway

Application Server takes the request from the user and if the request requires data then it connects to the database server and gives output.

Process for applying patches are:

• Download patches from the service .sap.com to Trans Directory
• Using CAR command extract the patches in the Trans Directory
• Using SAPM, import patches into SAP level and Apply

Transport can be done through STMS_IMPORT or through FTP.

• Customising Request
• Workbench Request
• Transport of Copies
• Re-location

Business KPIs are Key Performance Indicators. It indicates the performance of a company at a strategic level. They help in leading the company on the desired track by comparing company’s previous performance with the market leaders in the same market.

Table T000 contains a list of defined clients, where we can maintain transaction code SCC4.

SAPS stands for SAP Application Performance Standard, which is a hardware independent unit which describes the performance of a system configuration in SAP environment.

Central Instance has message server and dialog, update, spool, enque, gateway, background work processes.

Application server has dialog, update, spool, gateway and background work process.

By code sm51 t-code we can see whether it is Unicode or non-unicode. In this code we can find the release notes button in the application tool bar if you click on that you can see the total information like Database, Kernel version, Unicode or non- Unicode.

Four types of transport requests are there

• Customizing request
• Workbench request
• Transport request
• Relocation

For communication between systems within the landscapes logical system is required. It enables the system to recognize the target system as an RFC destination.

TCODE used is SPRO

To assign an object to 100 roles at time,

• Go to sell T-code from there go to the table agr_agrs.
• You will be asked for Access key
• Enter the objects that needs to be added to 100 roles
• Select the range of roles in which the object needs to be added
• Save or Activate whatever option is given

By using table “DEVACCESS” you can get a list of the users with development access.

To view locked transactions you need to look in field CINFO, table TSTC. Within SAP you can either use SE11 or SE16 to browse the table contents. Make sure that you enter “A0” as the “HEX01 data element for SYST” starting value and “A9” as the ending value. This will list all the transactions locked in the system.

OK code is used by a program to execute a function for example after a pushbutton has been clicked. A transaction code is a “shortcut” that helps a user run program.

• Login to your Transport Domain Controller
• Run STMSàOverviewàSystem
• Choose the system you want to disable ‘Import All’
• Go to Transport Tool tab
• Add/Create parameter “ No_IMPORT_ALL” set its value to 1

• Goto Tcode SNOTE
• GOTO MenuàDownload SAPNote
• Give the Note No
• After downloading check the status, if implemented
• Select Note, GOTO Menu SAPNoteàImplement Note

This table stores passwords and User IDS.

Kernel replacement is the replacement of the SAP executable on the OS level, while support package contains fixes to the ABAP code within a SAP instance.

Return code (4) indicates import ended with warning.

Return code (8) indicates not imported ended with error

Return code (12) indicates import is cancelled.

Return code (16) indicates import is cancelled.

You can do a client copy using the SCCL transaction

Synchronous Transport – Dialog or batch process are blocked until import is ended

Asynchronous Transport – Dialog or batch process is released after import is started.

Go to SM51 , Click Release Notes. Entry corresponding to ICU Version will tell you whether your system is ASCII or Unicode.

There are 4 types of transport requests in SAP –

• Customizing Request
• Workbench Request
• Transport of Copies
• Relocation

In consolidation route – objects can be changed and they can transport from one system to other. This is the route between development to quality

In Development route – Objects can not be changed and they can not be transported from one system to other. This is the route between quality to production

You can set the logon group using SMLG transaction.

Default SAP systems are pre-installed with English and German.

SAP does support many other language which may not full translate from the default English and German. To fill this gap , Supplementary language (a program) is installed.

NO . SAP is not a database but it uses databases from other vendors like Oracle. Although SAP has recently released its own database HANA

ST02 , RZ10

Basis is primarily a collection of R/3 system programs which present the user with an interface. By utilizing this interface the user can initiate the ABAP/4 programs. This is like an operating system for R/3 it sits between the ABAP/4 code and the computer’s operating system.

In order to maintain the roles in the SAP system, user can use transaction code — PFCG

• SAP Note: is an error in a single transaction or program and this is removed by implementing a SAP note.
• Kernel: Kernel encompasses the executable files (.EXE) like other applications and when a Kernel is performed using a new version of the EXE file replaces the older versions.
• Support Package: SAP support packages is a bunch of corrections, this can be utilized by applying the transaction SPAM

For multiple login on single instance, a client is used in SAP system. User can create multiple clients on a single instance. Client administration also provides data security in which, one user with one client cannot see the data of the other user with another client.

Table DEVACCESS will show the required details.

Transaction code SM12 is used Display and Delete locks objects

Please use Tcode rz20 in order to find dialog response time

Transaction code SCC3 can be utilized for monitoring the process of client copy which is functioning in the background or validate the log of front-end process.

• User logs into the client where he wants to transport ABAP package.
• Now use transaction ‘scc1’
• Then transport the request which entails the ABAP package

SGEN is an ABAP compilation. User can utilize the transaction SGEN in order to generate ABAP loads for a number of programs, classes, function groups, and so on, also for Business Server Page applications (BSP applications).

Check AGR* tables (e.g. AGR_USERS, AGR_1251, etc).

As of Basis Release 750, the background job scheduler itself validates whether a lock on the table BTCREMTCLN has been hanging for a longer period (at least 100 seconds). If so, the background job scheduler triggers the deletion of this lock.

• SMQ3 is ideally meant for exceptional cases which are then handled, and it’s not unusual that there are thousands of entries accumulating.
• There is a report meant for cleanup SMQ3 entries, RSTRFCIT, however, this accepts TID and queue name as input.
• Therefore, there is no option available as such in case so many queues need to be deleted.
• Another option is that you may write a Z-report with function module TRFC_QINS_DELETE_QUEUE which deletes the mentioned saved queue

Please follow the steps below to get user details:

• User Opens the transaction SM04 at application server where the session is functioning.
• Select the line of the user which must be analyzed.
• User Opns the menu User -> Technical Information.
• Now the complete output of the session is displayed.

For saving output in a file:

• Once output is opened, access Either via Menu List -> Export -> Local File OR press F9
• Please select the ‘Unconverted’ format.
• Now, at last, save the file on your machine.

A database committed in the Reports RS2ADRCL and RS3ADRCL during the client copy. As the reports delete all the address tables and all records deleted till the next database committed to the log files, the log files can result in an overflow.

LDAP Dir.

T-code-SMLG; It allows you to dynamically distribute the SAP users to application server instances. You can increase the efficiency of individual work groups by setting up multiple logon workgroups that consist of one or more application instances.

Tr. and R3trans

Roll-in:- The amt. of time needed to roll user context info. into work process.

Roll- out:-

Response time:- Starts when the user request enters the dispatcher queue end when hte next screen is executed to user.

Wait time:- This is the time a user request sit in the dispatcher queue. (means It start when the user request is entered in the queue and end when the request starts being a process)

Use br tools for backup at os level

In case if ur sap system down firstly checks ur network connections next see that all ur sap services are up and running i.e 3orcale services and 2 SAP services

Oracle services are:

• oracle agent
• oracle sid
• oracle listener

SAP services are

• SAPOSCOL
• SAPSID_SNO

If the services are stopped bring start these services and bring down the sap and bring up the process view after that go ur console management and see the work process are up and running.

>]Importing the request from the command prompt:

• tp add to buffer K9######
• tp import (target_SID> K9#### Client #

>]The common errors encountered during transports are:

• 0- successful transports – shows green color
• 4- successful tansports with warnings – yellow color
• 8- unsuccessful transports – red color
• 12- fatal errors

First, we have to go to su24 it shows the relation between objects classes and t-codes there we find all the object classes and authorization objects copy those missing object classes & authorization objects and paste in the s_tcode manually and do the user comparison then that user will be authorized to that transaction.

You can go su10 where su10 is a mass user creation just unlock those 15 users by using the symbol unlock so that the user will get the previous permission and can use the user.

Go to rz10 t-code which is used for (profile parameters)take the Instance profile and Extended maintenance display hit on change icon button. It displays the list of parameters change the parameters by (copy) go back and again(copy)go back and save after that bring down SAP Console management and bring up so that we can see the change in the parameters in the work process

Central system will have 5 wp and 2 services so that enqueue will reside in central system i.e (c.i+dbi) without the central system dialog instance cannot be loaded i.e application server so that all the dialogue instance(application servers) depends on one enqueue work process that enqueue wp resides in CENTRAL SYSTEM but any individual appl servers do not have a enqueue.

For 50GB of data with help of export and import method, it takes almost half a day. Instead of DNG export and import method you can do the system copy it takes less time than export and import Cmg to remote client copy for sap_all it takes 3hrs and for other i.e sap_usr,sap_cust etc its take 5to 10mins bcoz we have only 90tables in this and in sap_all we have more than 52902 tables so that it takes much time.

Based on the priority i.e class A, class B, class C background jobs run when u give the highest priority to program or package it runs accordingly…boz one thing in background wp we do not have any particular time to complete the give particular program or package so that it takes time (therefore it is known as answer for long running jobs is known as background wp) if u want the job to be done immediately run the progrm immediately so that it goes to dia wp and completes the work in the specified time.

Transaction SCC1

Connect to the machine and kill the ISP connection after opening a maintenance window, and see if this helps in killing your connection. It can be repeated at will until the users believe that the ISP was the problem.

To execute a function an OK Code is used by a program for instance after the clicking of a push button. A transaction code helps a user run a program as it is a “shortcut”.

To view Table TSTC, you can use transaction st11. Using transaction se93 you can define a new t-code.

In Transport Domain Controller you should login. STMS->Overview->System should be run. The System that you want to disable import all should be chosen. Transport Tool tab should be selected. Parameter “NO_IMPORT_ALL” should be Added/Created and set its value to 1.

Dialog (D), Update (U), Enqueue (E), Background(B), and Spool(S).

SAPGUI should be logged in to, and click Alt-F12 -> About

Trying to get every remote user connected to a network share, web help is easier. You can setup your own website if you don’t want to use SAP’s help site. On your business’ network structure, the best route depends.

OSS notes: http://service.sap.com/notes

SAP help: http://help.sap.com

Google: http://www.google.com

Yes, on a single box, it is possible to have more than one instance. Using a different SID and a different system number is the key here. It is also important to note that for 1st instance SAP recommends a 20 GB swap space and 10 GB per each additional instance for a 64 bit SAP kernel.

These are the same sometimes; For example, Client Refresh is when you are performing a copy to an existing client for the express purpose of updating the data. It is more appropriate to say “client copy.”if you are copying to a newly created client. A client copy from production to a QA server or from production to DEV server is really a client refresh and this is another way of thinking about it.

A list of defined clients is contained in Table T000, which with transaction SCC4 can be maintained.

User IDs and passwords are stored in this table.

In table USR40, the Answer:s should be placed.

Object directory entries are contained in table TADIR.

Development classes and packages are contained in Table TDEVC.

Information about change requesets are hold by the following tables. E070 Change request headers E071 Change request object lists

Table DEVACCESS

Within transports E071K Object keys are contained.

The table TRBAT should be checked.

A list of repaired objects and their access keys that have been repaired can be found in ADIRACCESS.

Implement this parameter in the instance profile: login/disable_multi_gui_login = 1 to disable multiple user logins within the same client. Users have the ability to ignore the warning window at the time of login to the same client if you do not use this parameter in your system. If you get audited, activating this parameter in your system will make you look good! What would happen in case of exceptional logins? You can implement parameter login/multi_login_users, in case you’re wondering how to allow multiple logins for certain key users. If the parameter above is active in your system, you can list the user IDs that should be ignored.

Via SM01As one can lock/unlock transaction codes. But, how viewing the transactions that are locked in the system can be managed? Field CINFO, table TSTC should be looked into. To browse the table contents within SAP, you can use either SE11 or SE16. You should Enter “A0” as the “HEX01 data element for SYST” starting value and “A9” as the ending value necessarily. All the transactions locked in the system will be listed by this.

Note: “HEX01 data element for SYST” is the CINFO field description.

Via SU01 (User Maintenance.) user accounts can be locked/unlocked But, behind the scenes what actually goes on? To actually set this what does the system do? Update the table USR02. If the user account is locked or unlocked is determined by the field UFLAG. The user account is locked is indicated by value “64”. The user account is unlocked is indicated by the value “0”. At the database level you can issue an update statement that locks all users in mass. Although you should not lock yourself out! For super user accounts in your update statement, exceptions should be used. The locking/unlocking has been made a bit easier by improving 4.6b and above to this kind of task. However, it is just one simple query that changing at the database level is much faster.

The process is controlled by TP and several tools are called, like r3trans but also e.g. DDIC-Activation.

Yes, some things which other IDs cannot are done by DDIC which is hardcoded. In SE11 using a SAP_ALL user, you should be able to activate tables. For basis login accounts (SAP*), 06071992 is the default username and password.

Valid user passwords, accounts, default login directories and user security permission levels are contained in /etc/passwd. user:password:UID:GID:login_directory:shell is the file format.

Shorter pathnames should be used.

You will be asked for a key during the installation, which solution manager can only generate.

Paging space should be increased to 20 GB.

On the installation CD look for SAPADMIN and SAPSETUP. Then, to distribute this program use a utility such as Microsoft’s SMS or to call the SAPSETUP program use a login script.

The control panel should be selected, and then the SAP console administrator should be selected and general tab.

The global system change option (SEO6) to modifiable should be set for all namespaces/objects in our DEV system. Ability to change any, including SAP, namespace/object should be possessed by the developer. The client options (SCC4) should be changed to “changes which is allowed for repos and cross-client cust” and radio button should be changed to “auto. The changes.”should be saved. Next, the CATTS sessions should be enabled.

You should not use sapconnect in versions with basis release 6.20 or higher. The mail server should be placed in the SMTP node in SCOT directly.

The source for the cover page should be found. Either it will be from SAP itself or from the OS spooler. Then appropriate action should be taken.

No, but tables associated with the transaction code can be analyzed and see what this user has done if there is a username field that traces.

A report to run from DB13 other than pre-configured DBA jobs cannot be scheduled. Use SM36 instead of this and make event-driven jobs.

The transport group is misconfigured for QA. Go to Overview after going to STMS. Choose communication by double-clicking on QA. Next the correct transport group should be entered and save.

Using config-tool you can create a second server process. Also through SCS, load balancing is possible.

These parameters from TPPARAM can be deleted.

A SAP Web dispatcher is needed. SAP Web dispatcher routes SAP ICM traffic while acting like a SAP Router. A BSP that sits on the ICM is BW Web reporting. In the kernel directory you can look for sapwebdisp.exe or by using command option “bootstrap.”do a self-generated profile.

SMTP comes built in to kernel, starting with version WAS 6.x. Select transaction. Configure and SCOT it there.

The solution to this is to restart the system. You may be missing the profile parameters if it is an add-in and you have restarted your ABAP then. Look in the work directory and check dev_icontrol if this is okay and a restart does not help. Apply a patch to solve the problem if the J2EE engine software is the problem.

The error messages indicate that one of your load jobs run unsuccessfully.

In “my signature”, “my links”should be used along with the keywords: PXA Buffer.

Yes. SO16-> Tab Mail Sys group-> bottom radio button pathway should be followed.

To update data (RFC calls) you can call SAP functions directly. To try and manipulate data directly at the database level (sql scripts, jdbc) is not recommended. In general to update tables directly in SAP is a very bad idea.

The CI instance with the right system number should be reinstalled.

To store another copy of your archive log, log on to another drive/server in your init.SAP file.

ABAP RSPARAM program should be run. The real value of the SAP parameter and where they have been set up can be obtained by this. 10,000 entries can be hold by the lock table, which is over enough for the average system. It is possible that the developers should modify it if the program is not written properly.

Under “subsequent steps” section read the Homogenous System Guide and follow all directions. Transaction codes BDLS and SALE should be checked as well.

The SAP ABAP program buffer and other buffers are emptied when the server is restarted. During the first run, as far as performance goes, the reports runtime will be a bit longer. Without harm, the system can be restarted every week. The SLA/users demand may be the only reason against it.

The DB as PRD on your new system should be opened first. Second, the redo logs should be applied. Next, to change SID the script should be run. If using WAS 6.10 or above this will change SID but will not change tablespace names.

There are many predefined indexes in SAP. Via DB02->checks-> database ->ABAP dictionary ->display one can see these indexes. You see all indexes of which the definition is created in the dictionary under optional indexes, but at database level it has not been created.

On each transaction it depends. According to system function, production or test/develop/demo/etc. it is sometimes determined by other configuration and sometimes it is set.

Enter the variant name and choose the attributes radio button in transaction SE38. The field can be set to “selection variable.” You can define that it is SY -DATE+7, under selection variables button.

RFC is the abbreviation of Remote Function Call. This is a type of mechanism which helps in communicating as well as exchanging various types of information across the other SAP systems.

Mainly four types of RFC are present. These are namely,

• Synchronous RFC (S RFC)
• Transactional RFC (T RFC)
• Asynchronous RFC (A RFC)
• Queued RFC (Q RFC)

Transactional RFC allows the processing of the sent request for an error in the system, only once. This is done after allocating an ID for the transaction process which is also known as TID. It is different from asynchronous RFC only in this aspect. The availability of the remote system is not necessary at the present moment in the T RFC.

JSPM is the abbreviation of Java Support Package Manager which is used in order for the application of support packages on the deployed components of the software. Basically, JSPM is an important tool that helps in the installation of the packages and also all the components. To deploy packages, JSPM often uses SDM.

On the other hand, SDM which is the abbreviation form of Software Delivery Manager helps in importing Support Packages of Java. This is also used for deploying software packages and also used to manage them. These packages are said to be received from SAP.

SAP note is used to implement the removal of errors in a single program or a transaction.

The kernel is the one that contains .EXE files which are also known as executable files. The older version of these files gets replaced after Kernel gets upgraded.

Support packages are basically just corrections.

SAP system defines SAP singlet stack system. These can have two types of runtime engines like JAVA or SAP Netweaver as ABAP. An example – Single Stack System (JAA) is basically SAP Enterprise Portal System (Ep). On the other hand, Single Stack System (ABAP) is basically SAP ERP (ECC).

The chief responsibilities of the SAP Basis Administrator are as follows –

• Configuration as well as installation of the system.
• The management of performances of various kinds of components.
• Load server balancing.
• Management of integration and interfaces with servers.
• Managing various kinds of servers and services provided by them.

There are five different types of user systems in the SAP system. These are as follows –

• Dialog user – Mainly for accessing the interactive systems from GUI, this type of server is used.
• Communication User – For external RFC calls, this type of user is used.
• System User – System User mainly helps in the background processing and intra system communication.
• Service User – Anonymous and a large group of users mainly use this type.
• Reference User – Allowance of assignment of extra authorization is done by this user. These are not related to persons as users.

SAP GUI is basically a client tool that helps in accessing the central server and also runs on various operating systems like UNIX, Microsoft Windows, and Mac etc. SAP applications like the SAP Business Intelligence System and SAP ECC are all managed by SAP GUI.

There are mainly three standard clients and these are as follows –

• 000 – This becomes available with the installment of the R/3 system. This is also known as the master client.
• 001 – Basically, 001 is just a copy of 000. It has a test copy. In order to create new clients, this is used.
• 066 – This client is known as the SAP Early watch. If diagnosis and monitoring services are required in the SAP system, this is used.

New client can be created by following these steps –

• The transaction code which is to be used in order to create a new client is SSC4.
• Click on New Entries and put the details like City, Client number and name and Currency and the Roles, etc.
• Data specific to the client needs to be entered and permission must be set.
• Click the save option.

SAP system can be locked or unlocked in two ways –

• Manually or forcefully
• Automatically

For single-user and for multiple users, transaction to be used is SU01 and SU10 respectively.

The conditions must be specified in order for the background job to be started. This is said to trigger the starting of the job. The following are the different kinds of start conditions that are to be used in order for the background job to be started –

• Immediate
• After Job
• Date/Time
• After Event
• At Operation Mode

The categories are as follows –

• Class A – High Priority: This category is mainly used for very critical and urgent tasks. Hence, these tasks also get scheduled with class A priority job. Maybe one or more than that background work process gets reserved by a Class A job.
• Class B – Medium Priority: After the Class, A priority jobs get completed, these types of jobs get executed.
• Class C – Low Priority: After the completion of jobs of classes A and B, the job of class C gets started.

Users who are working the SAP system mainly use SAP GUI for Java or SAP GUI for Windows.

For users who are working as ABAP developers, SAP GUI for Windows is used.

• When the operating systems of the users are not Microsoft, SAP GUI for HTML and SAP GUI for Java are mainly used. However, they can also use SAP GUI for windows.
• For the integration of Dynpro transactions to the Portal, mainly SAP GUI for HTML is used. Dynpro-based applications are well integrated with the help of this, into the portal.

Instances in the SAP system get created when the system gets installed and configured. Processors, memory, and other resources get referred to by these instances. Various sources can be shared by users after logging in to the system. This is also allowed by the SAP instances. These are managed by CCMS. Users use them to log in to the SAP system. One or even more than one instance can be present in the SAP system. Using only one CCMS, only one instance can be set up in the system. Two or more of those instances can be used to configure the system.

Data sharing across the SAP system is not available in the private mode as these data are allocated to specific users exclusively. Due to the exhaustion of the extended memory, this type of mode occurs.

When all the other users are online, the SAP patches can’t be installed. This is because these patches will not be able to be updated and terminated by the support manager. Hence, the best time to install SAP patches is when there is an absence of users’ login in the SAP system.

The object directory entries are included in the table TADIR.

The list of repaired objects gets stored in the system including ADIRACCESS keys.

Parameter Tab cab is used to allow access to the T-code which is assigned to the users to work on.

Personalization Tab can be used to connect RFC across the various systems.

In service users, passwords are not checked as the rights over the passwords are only entitled to the admin. Users can’t make changes to the passwords. Anonymous users use service users. Multiple logins are also possible.

GUI login is not possible for the reference user. User authorization from one user to another is made possible by this during an emergency.

Logon groups are mainly defined with the help of Tcodesmlg. At first, the group needs to be created and then the instances are to be assigned for those groups.

SAP installer that is SAPinst.exe is to be employed in order to use or install JAVA patches. These patches can be deployed with the help of JSPM or also known as Java Support Package Manager and SDM or also known as Software Delivery Manager.

Data transfer can be successfully conducted with the help of using BDC. There are three functional modules namely,

• BDC_OPEN_GROUP: In this module, mainly the client and sessions as well as the user names get defines specifically.
• BDC_INSERT: Data can be inserted from one session to another with the help of this module.
• BDC_CLOSE_GROUP: Mainly used for closing the batch input session.

Client refresh mainly includes copying or overwriting to an existing client. However, if the newly developed client gets copied, this is called client copy.

The full form of business KPIs is Key Performance Indicators. The performance of a company gets indicated strategically with the help of KPIs. The performances of the company get compared with the growth of the company. In this way, KPIs help in leading the company by keeping a good track. It also helps in doing a comparison between various market leaders.

The SAP system gets installed with German and English as the default language. Supplementary language gets installed in order to get other languages.

• Database
• Operating system Interface

• Database layer

SM12 is the transaction code that manages SAP lock entries.

Transaction Code SM04 used for displaying the user list.

• Job Scheduling
• Job Processing
• Job Overview

Spool asks for are produced amid discourse or background processing and put in the spool database with data about the printer and print arrange. The genuine information is put in the Tem Se (Temporary Sequential articles).

Go –> SAP Management Sonsole –> “system logs” Under SID {or} You can check “/usr/sap//system/logs” directory.

• Return code 4 – Imports with warnings
• Return code 8 – Imports with errors (Syntax, Program generation, and Dictionary activation errors)
• Return code 12 – Specifies Import Cancelled
• Return code 18 – Specifies Import Cancelled

The purpose of the SAP T000 table is you can view the list of users those are defined in the SAP system.

USR02 table is used for finding the user login details.

A maximum of 312 profiles/roles we can assign to users.

Several possible reasons can be responsible for this. To a printer, the spool is sent and deleted. The housekeeper deleted the spool if it is too old. Also, some test reports rollback after simulating a calculation then. Online it works fine. The spool is rolled back as well when a background job does a rollback.

SAP basis acts as an operating structure or a stage for SAP applications to run. It supports the complete range of SAP applications.

In private mode, the heap data is wholly billed by the user and is no more communal or obtainable across the system. This occurs when your comprehensive memory is tired.

OCM refers for online correction system; by using SPAM you can relate OCM Patches.

Transactional RFC permits giving out of the sent request for a mistake in the system, only once. This is done after allocating an ID for transaction procedure which is also known as TID. It is dissimilar from asynchronous RFC only in this feature. The accessibility of the remote system is not essential at the present moment in the T RFC.

SAP system describes SAP singlet stack system. These can have two kinds of runtime engine like JAVA or SAP NetWeaver as ABAP. An example Single Stack System is SAP Enterprise Portal System. On the other hand, Single Stack System is essentially SAP ERP.

SAP GUI is a custom tool which helps in accessing the central server and also runs on different operating systems like UNIX, Microsoft Windows, and Mac etc. SAP applications like the SAP Business Intelligence System and SAP ECC are all managed by SAP GUI.

When other users are online, we can’t fit SAP patches, as support manager will not be able to inform and it will finish it. So it is always possible to better apply hold packs when there is no user’s login into the system.

Some of the steps are:

• Go to STMS T-code
• Go to menu option overview
• Select System
• Choose SAP System
• Go to transport tool tab
• Create parameter “No_Import_All” with the value set as 1
• Save it

Personalization Tab: It is necessary for RFC association between systems other than user individual information

Parameter Tab: It will allow admission to assign T-code on which one has to work

Logon groups can be distinguished using the Tcode smlg in order to do that you have to make the group and then allocate the instances for that exacting group.

To use the JAVA patches, SAP installer (SAPinst.exe) is in use. SDM and JSPM are the newest versions of tools used to organize Java Patches.

To resolve queries which cannot be solved by using the technique interfaces, a set of information is utilized. This place of information is known as “Data Sets”.

A list of steps amid t-code is known as logical LUW

Client refresh is overwriting or copying to the obtainable client while impersonating the recently created client is called client copy.

The idea of TDEVC contains progress classes and packages.

Some of them are:

• Update
• Background
• Dialog
• Enque
• Spool
• Server

Application Server takes the demand from the user and if the demand requires data then it connects to the database server and gives the output.

Transport can be completed through STMS_IMPORT or through FTP.

The types of transport queries are:

• Relocation
• Customizing Request
• Workbench Request
• Transport of Copies

To view locked transactions, you require looking in the field CINFO, tabling TSTC. Within SAP, you can use SE11 or SE16 to surf the table contents. Confirm that you enter “A0” as the “HEX01 data constituent for SYST” starting value and “A9” as the ending value.

This table stores passwords and User IDS.

Go to SM51, Click Release Notes. Entry equivalent to ICU Version will tell you whether your scheme is ASCII or Unicode.

NO. SAP is not a database but it uses databases from other sellers like Oracle. Although SAP has lately released its own database HANA

ST02 , RZ10

You can do a client copy using the SCCL transaction.

So, these are the following interview questions & answers for SAP Basis jobs, one should go through it and search more to clear the job interview.

Basis is primarily a collection of R/3 system programs that provide an interface to the user. The user can start ABAP/4 programs by using this interface. This is similar to an R/3 operating system; it sits between the ABAP/4 code and the computer’s operating system.

• SAP Note: is an error in a single transaction or program and this is removed by implementing an SAP note.
• Kernel:Kernel encompasses the executable files (.EXE) like other applications and when a Kernel is performed using a new version of the EXE file replaces the older versions.
• Support Package:SAP support packages are a bunch of corrections; this can be utilized by applying the transaction SPAM

• First, ensure that your network connection is working properly.
• Next, ensure that all of your SAP services are operational.
• Examine the database’s status.
• SAP Administration Console (Dispatcher, IGS and Message Server)
• You must determine the trace root based on the point at the serial no (c)

The different work process types are

• Dialog (D)
• Update (U)
• Enqueue (E)
• Background(B)
• Spool(S)
• Message
• Server
• Gateway

PFCG, after which we generate the profile and assign roles to users.

Solution: In the SAP system, a client is used for multiple logins for a single instance. On a single instance, the user can create multiple clients. Client administration also provides data security by ensuring that one user with one client cannot view the data of another user with another client.

Solution: The primary responsibilities are as follows:

• Installation and configuration of the system
• Server load balancing
• Different components’ performance management
• Managing interfaces and server integration
• Managing servers and various services

• System Trace: A system trace is used to record internal SAP system activities. The trace can be used to diagnose internal issues within the SAP system and the host system.
• The System log is used to view the most recent logs for the application server and CI.
• In the event of a problem, the developer traces, or records, technical information about the error or problem.
• The log is used for problem analysis and system monitoring in Developer trace or System.

Background jobs run based on priority, i.e., class A, class B, class C. When you give the highest priority to a program or package, it runs accordingly. Because we do not have a specific time to complete the given program or package in background wp, it takes time (therefore it is known as the answer for long running jobs is known as background wp) if you want the job done immediately, run the program immediately so that it goes to dia wp and completes the work in the specified time.

It takes nearly half a day to export and import 50GB of data using the export and import method. Instead of using the DNG export and import method, you can use the system copy method, which takes less time than exporting and importing Cmg to remote client copying. For sap all, it takes 3 hours, and for other tables, such as sap usr, sap cust, and so on, it takes 5 to 10 minutes. This is because we only have 90 tables in this, whereas sap all has more than 52902 tables, so it takes longer.

Connect to the machine and, after opening a maintenance window, kill the ISP connection to see if this helps you kill your connection. It can be repeated indefinitely until the users believe the ISP is the source of the problem.

These are sometimes interchangeable; for example, a Client Refresh is when you perform a copy to an existing client for the sole purpose of updating the data. If you are copying to a newly created client, it is more appropriate to say “client copy.” A client copy from production to QA or from production to DEV is really a client refresh, and this is another way of looking at it.

TPPARAM parameters can be removed.

The transport group is misconfigured for QA. Go to Overview after going to STMS. Choose communication by double-clicking on QA. The appropriate transport group should then be input and saved.

It is necessary to locate the source of the cover page. It will either come from SAP or from the OS spooler. Following that, appropriate action should be taken.

When the server is restarted, the SAP ABAP program buffer and other buffers are cleared. In terms of performance, the report runtime will be slightly longer during the first run. The system can be restarted once a week without causing any harm. The only reason against it could be the SLA/user demand.

The database system includes a set of system tables that contain information about database objects and their relationships with one another, as well as statistics system tables, monitor system tables, and loader system tables. For system tables, we normally search at SE16.

Three system profiles can be found in SAP directories.

• Instance profile.
• Default profile (also known as system profile)
• Start Profile.

A domain controller is simply a server that has AD (Active Directory) installed.

Yes, can modify the profile parameter at the OS level. It is not advised.

First, go to su24, which displays the relationship between object classes and t-codes. There, find all of the object classes and authorization objects. Copy those missing object classes and authorization objects and manually paste them into the s_tcode, then do the user comparison, and that user is authorized that transaction.

An OK Code is used by a software to run a function, such as when a pushbutton is pressed. A transaction code is a “shortcut” that allows a user to execute a program more quickly.

A local printer is referred to as a “L” access mechanism. It is specific to the SAP server and not the user. Front end printer is referred to as an “F” access technique. This method makes use of the user’s Windows printer.

In your SAP system, two users “OPS$adm” and “OPS$SAP” Services are formed, and this user mechanism is utilized to interact and communicate with the database inside.

First, download the fixes from the.sap.com service to Trans Directory. Extract the patches from the trans Directory using the CAR command; then, using SAPM, import the patches into the SAP level and apply them.

A restart is often the answer. If it is an add-in and you have restarted your ABAP, the profile parameters may be missing. If this is correct and a restart does not help, go to the work directory and search for dev_icontrol. If the J2EE engine software is the source of the issue, a patch will resolve it.
