BDC background run error but frontend is OK
I have trouble to run a BDC for TCODE F-53, I use SHDB ti record a BDC, and I can run it in MODE A (frontend), and successfully return a document number.
But when I run it in background mode, an error happens.
The field " reason code" in reqiuired in our system. I DO input the field in the BDC and record it. but when run background, it always said, miss "reason code".
Is there anyone have the similar situation like me? And What is the solution??
Thanks for your help in advance.
