I would like to be able to correct a deferral code after an invoice is posted. Voiding an invoice just to fix an accounting deferral code is terrible from the customer's perspective as their invoice number and such will change. Having an 'easy button' that will allow us to correct the deferral code after posting would be ideal. Whether it's a missing deferral code or an incorrect one, there has to be a way of voiding just the deferral part and re-doing it after the fact.
