Error Message - While posting billing doc, Assign accounting assignment object PSG/A000 123 to a profit center
Need your support, Purchase order has been generated from one company code 123 and this is interco transaction and the material is already assigned to Profit center (old profit center was assigned and then revised to new profit center) but the PO has old profit center and plant and the delivery document was posted. But when the billing document is generated it's not picking the profit center and this is blank.
Now these documents are from 2022 and we cannot reverse PGI or PO, as there is no SO (no changes can be made).
We tried updating the Material with old profit center (as there were no open PO or SO generated for this material in current year) but the system is not accepting this change and still show the same error, please advise how to solve this?
