Issue in document posted by BDC
I am trying to work on an issue. There is a BDC program that posts the accounting document using FB01 transaction. After I complete the posting and I view the document posted in FB03 transaction. I then view the Profitability Analysis Document in Environment->Document environment->Accounting Documents->Select Profitability Analysis doc number. I notice that the sales quantity and revenue in the Value fields tab is incorrectly posted.
I need to resolve this issue. Am I looking at a user exit? How do I find out which User Exit I need to debug? How do I do it (I cannot hardcode breakpoint in the include)
