we are not creating COPA document through TBB1 run, Sorry for wrong information. (Initially I was communicated like that from functional)
If you are not creating CO-PA document from TBB1 run, then my advise is not working for you.
So again, can you tell me pleas, how do you create CO-PA document and how it is related to TRM?
Only then i can tell you, what you need to do.
