Special order purchase order requisitions are converted to vendor purchase orders using the PO Requisition Management program. Since specific purchase order lines are placed for each special order sales order line, and since these PO lines are used to fulfill the special order sales order line, the system does not include the open quantity for the special order purchase order lines in the On Order Amount that is maintained for the item. Converting a special order PO requisition to a special order purchase order does not result in an update to the inventory quantities that are maintained for the item.
