I need to migrate contact persons into ISU. So I created a BDC using BUA1 and it imports data fine.
BUT, I can't get the key generated to store in TEMKSV. I tried populating the Application Area with R1, Message Number with 425 (which is what I get when I save in BUA1) and message variable 1 (also tried 2, 3 & 4).
I get a short dump telling me that the return field was not found or the message variable is initial.
Can anybody point me in the right direction here? I'm not sure what I'm doing wrong, and can't find anything in the docs about this specifically.
