If a GL account is updated in the Billing Year/Setting information, it should retroactively change the account number for unposted transactions that the change effects. Having to manually adjust credit and debit accounts for each transaction when you have accumulated over 400 transactions is very time consuming. There should be a pop-up notification to notify the user that a change has been made to a GL Account and ask if we want to retroactively adjust credit/debit account numbers for all unposted transactions.
