Dear Madhuri ..
You mentioned is How to bring stock From Customer and sending to vendor Right
This is special process
Coming to TASG Item category , i have to tell you How credit memo is created in Third party process
I Am telling as per My knowledge
First create Return document in va01-- now save
Now create credit memo ....with ref to VA01 Return order no
While maintaining in VF01 Maintain Billing type G2S Only Not G2
Coming to TASG Item cat in copy control we have to make Between TAS --TASG Item category level In the Sales document type to Billing document type source and Target doc.
Dear Mentors please Tell me if i am wrong .
Thanks a lot
