I know that heading of the document is scary but SAP does allow postings to previous fiscal year. Our GL and AA ledger were inconsistent due to mid year legacy asset load (AS92) and GL load performed in previous year. Run report RAABST02 to find the inconsistencies. With some research, found that you can post to previous year book to correct or adjust these values to reconcile. Weird but true… SAP allows you to post to assets reconciliation accounts only through transaction ABF1 with posting keys 70 – debit and 75 – credit. Use transaction type 100 for posting key 70 and transaction type 200 for posting key 200. These posting keys allows you to post to asset reconciliation accounts only
