HI Christian,
Thanks for your reply. Let me tell you the issue, while creating the BP in CRM I am getting the language field, but even after the filling the language field, it still got stuck in SMW01 saying "fill up the required fields" but no other fields is marked required in R/3, I already made all other fields optional.
I was very confused, and then I debugged the bdoc, and queue and saw in R/3 XD01 screen the language field is causing the issue. Now I am not sure how to resolve this. Cause I've already filled up the language field with right value, still i am getting the error.
Please help.
Regards
Rahul
