I have a question on updating XBLNR. Initially the billing document was populating in reference field in the accounting document. All of sudden some config went in, and in the reference field, PO number is getting populated. Now we fixed the issue and we are getting billing document number in refernce field in accounting document. We have 1000 documents with incorrect data in reference field. Is there a way to update the incorrect reference field data with billing document for the accounting posted already. I can do it manually by change mode in accounting document change the reference field data to billing document. But i cant do it manualy for 1000 plus documents.
Please let me know.
