Withdrawals and/or deposits are cleared in the Bank Reconciliation and the reconciliation is posted. The subsequent reconciliation still shows those withdrawals and/or deposits on the reconciliation list.
This is a known issue in Sage 300. An item is marked as cleared and yet it does not get removed from the list after posting, as it should. While this situation is inconvenient, forcing the user to scroll through more items than necessary on future reconciliations, there is no transactional impact on the subsequent bank recs. If the issue becomes too problematic, contact a support technician for some data manipulation.
