Use this tab window to enter a purchase order number and, optionally, a maximum release quantity for a specific part.The purchase order number should be the number of the standing purchase order to be used for purchase lines generated during the schedule release process. The maximum release quantity is an optional way of limiting the quantity of order lines on each purchase order. Whenever the maximum quantity has been reached, it is no longer possible to create any new purchase order lines on this purchase order. You then must connect a new purchase order to the agreement per part.
