I want to check a link between supplier's bank account (table LFBK) and payment mode (LFB1-ZWELS).
With the user exit EXIT_SAPMF02K_001, I usually get I_LFB1 and T_LFBK and I'm able to check what I need. But I have a problem with the transaction FK02 (change supplier's master data) when the user doesn't check the box ' Payment transactions' in the 'general data'.
In this case, T_LFBK is empty in the user exit, even if there are data in the database table LFBK for the supplier.
I could read the database table from the user exit, but how could I find the difference between the 2 following cases ?:
1) there are data in LFBK; the user doesn't check 'general data/payment transactions' in FK02; user exit gets an empty T_LFBK table.
2) there are data in LFBK; the user checks 'general data/payment transactions' in FK02 and removes all bank data (LFBK) rows; user exit gets also an empty T_LFBK table.
any idea ?
thanks in advance,
Henri
