I have an open customer order and in the sale transaction entry window, we have entered a deposit in the "amount received" box on the bottom left for a deposit we received a couple weeks ago. Now, the customer has canceled the order and I need to refund the deposit. But, I can't "remove" the deposit from the order because that fiscal period has been closed. It won't let me void the sales order until the deposit issue is resolved. How does one resolve this? We do not have the customer refund module.
