Sage 100

Sage 100 v2016.3 - user entered in invoice with date 11/2017 instead of 01/2017. They have split commissions which apparently precludes editing the invoice after the fact through AR Invoice Data Entry. What do I hurt if I manually edit: AR Invoice History Header, Open Invoice, Salesperson Commission files? And, am I forgetting any?

I would just enter a credit memo with the wrong date and a new invoice with the right date and move on.

I thought about that - customer has an invoice already printed with # 12345 - will Sage stop me from CM 12345 and re-enter invoice 12345? Otherwise, customer will pay the old invoice and the staff will be scratching their heads about why that old invoice is paid off. And this all will happen 30-60 days down the road.

AR_TransactioPaymentHistory will need the date changed on the I record.

If that customer has 100's of invoices every month for the same or similar amounts, it could be a problem. If they only have one or two, then your client should be able to trace the payment to the right invoice based on the amount. I'm a maverick when it comes to this kind of bookkeeping. :-) Or, when the payment arrives, enter it as a prepayment. Then offset it to the new invoice when it becomes apparent that they belong together...... Or........ Or......... :-) You get the gist, I'm guessing!
