Here are some of the questions that I had been asked and commonly expected if you have worked on badi :
- What is enhancement and how many types are there?
- What is implicit enhancement?
- How explicit enhancement differs from implicit?
- What are user-exits? If you have worked state an example.
- What is customer exit and how it affects standard program?
- Difference between enhancement-point and enhancement-section?
- Do you use commit after code in enhancement-point? If yes where have you used it? (Note : never use commit in enhancements , you can but it’s not a good practice as the enhancement can be called via other programs as well)
- Why do we implement badi?
- What is the use of badi? and what makes it a reliable method?
