Revision of purchase orders

You revise purchase orders when you want to change information, such as the quantity or the vendor, on a purchase order.

A purchase order must be in a status of Approved (APPR) or In Progress (INPRG) before it can be revised. You select the Revise PO action to create a revision of the purchase order. Each time that you create a purchase order, a revision number is generated, starting with 0. When you revise a purchase order, the purchase order number does not change. You can make numerous changes to the same purchase order. Changes that are made to a purchase order affect future transactions only. The changes do not apply to existing receipt lines or to existing invoice lines. You cannot revise internal purchase orders.
