Long story short, we are running 23R2 upgraded from version 8, with Weighted Average. Revaluation events cause SERREN+/SERREN+ to be not balanced. What seems to happen is at the first revaluation event that the system creates new M191 postings instead of all the old M3s. The result is that the accounting does not balance. M1 and M191 balances though. Removing the old M3s seems a bit unorthodox since they also have voucher numbers. Question:

• Is it safe to remove faulty postings (thereby removing some of the sequence numbers for a transaction)?
• Is this a known problem already? We have looked at corrected bugs in the upgrade script. However the upgrade script changes the posting control basic data from M3 to M191, but does not update old transactions.
