During SAP IS-U invoicing, rebate document is posted along with other charges and credits. When the collective invoicing is done, collective billing credit is posted which includes rebate document and other credits. Collective billing credit is posted in summarized form. We have a requirement to refund the rebate document. If the payment method is populated on the rebate document of the child account, then refund is not getting triggered. If we populate payment method on collective billing credit then the refund is getting issued. But the problem is refund is getting triggered inclusive of other credits as well.
Could you please provide few pointers on how to post the rebate document on collective account separately so that refund can be issued?
I have tried fqevents 2220 and 2222, 2225 but no success.
