Hi
I need a BAPI or FM to change field Reference Document Number (XBLNR) of an already posted document. These kind of documents that I need to change are posted from MIRO, so its origin is an invoice of a purchase order. I've checked this forum and found out few discussions making reference to FM FI_DOCUMENT_CHANGE. I've tried this FM and field XBLNR is changed in tables BKPF and BSIK, but it's not changed in BSIS, so I've dismissed this FM because it couldn't ensure data integrity. I've debugged the FM and it seems it's imposible to change BSIS-XBLNR from this FM because there are no UPDATE to BSIS that changes this field. So, anyone has any other option?
Thanks and regards
