Purchase orders
If you need items that must be purchased first, you can order these via a purchase order. You either add a purchase order directly or add it as a suborder to an existing order (request, work order, reservation, contract order, move order or maintenance plan order).
For each purchase item you order, you must add a purchase order line, stating the details of purchase and the required quantity.
Purchase orders can also be added in the Purchasing TSI as part of an integrated demand and supply process.
