Voiding payments
You can use Manual Forms Reservation (AP81.1) to void payment forms that were never issued; for example, a damaged payment form. Select the Void form action to void the payment forms.
You can reconcile, void, or stop payments, or reopen bank transactions that have completed the cash payment cycle. If a payment gets lost in the mail, is issued in error, or is no longer valid for any reason, then you can void or stop payment on the check. You can reinstate the invoice to reverse General Ledger payment entries and then create a new payment for the reinstated invoice, or cancel it. Use this procedure to void a payment.
