Dear Jurgen,
Thanks for elaboration
I did found scn link related to my problem....
IDoc for Creating Vendor and its address
Only difference being My all IDOCs are processed successfully but IDOC status for CREMAS is 51. As Mr. Abhishek Biwal has mentioned screen shot; Same is showing in status record for CREMAS.
I am not sure how did he figured out about custom code. Cause in our case also we did not do any changes from basis side.
Regards,
Arthur
