Manual Forms Reservation (AP81.1)
Use Manual Forms Reservation (AP81.1) to reserve payment numbers for manual cash payments. The reservation process is required only for payment codes that require manual payment reservation. The payment reservation process prevents duplicate system and manual payment numbers from being issued. You can unreserve a manual payment number as long as you have not applied an invoice to it.
You can also use this form to void payment numbers that have never been issued for payment, such as a damaged payment form.
