Question { IBM, 9212 }

5. What are the difference between BADI and user Exit.

Answer

In USEREXIT u code in the standard SAP program, hence any
updation in the version of the standard program will lead
to the loss of ur coding. But same is not the case of BADI.
Here the code remains outside the standard program.
You need to search for the suitable BADI as ur requirement
and then do the coding and plug in the program.

USEREXIT - It is also a program enhancement technique. here
also u need to find suitable userexit and code in ur
program.

14. How do you write UTP?(unit test plan)

Answer

Unit testing is done in bit and pieces. Like e.g. in SD
standard order cycle; we do have 1-create order, then 2-
delivery, then 3-transfer order, then 4-PGI and then 5-
Invoice. So we will be testing 1,2,3,4 and 5 seperately
alone one by one using test cases and test data. We will
not be looking and checking/testing any integration between
order and delivery; delivery and TO; TO and PGI and then
invoice.
