Yes. We should be able to correct the coding of the Credit Memo and also the date. We recently had a Credit Memo with a future date and we applied the credit and paid the vendor. Now the invoice paid is showing up each month as an unpaid balance.

Agree! You can't even delete them once they have been applied and the invoice paid, check cleared and reconciled. You have to make a manual journal entry to correct the account number at this point. Super frustrating. Allow adjustments just like invoices.
