Well this just came up today that a credit memo got applied to the wrong general ledger account. In chatting with support I either have to do a journal entry to back it out of the incorrect gl and credit the correct gl, or I have to un-apply the posted credit, delete the credit memo and reenter and reapply. It would be easier if you could just adjust the credit memo to to correct gl, as you can for invoices.
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.
