Canceling a purchase is process that relieves the line items on the purchase order.
You can cancel a regular purchase order at any time, if no receipts are entered on the purchase order record. You can cancel a purchase order by selecting Cancel Purchase Order from the Purchase Order menu. The status changes to “Cancelled order” or “Unprinted Cancellation Notice”, depending on the business rule selected in Configuration. The program automatically reverses any posted encumbrance balances during the next post run. You cannot reopen cancelled purchase orders.
