When the supplier has informed you that the parts are delivered to your customer and you have entered the direct delivery in your system, the purchase order is automatically closed. The status on the purchase order is changed from Released or Confirmed to Closed. The customer order receives the status Delivered and the customer can be invoiced. This assumes that no partial deliveries remain on either order. If the supplier has partially delivered an order and for any reason is not able to fully deliver the order, it is possible to manually close the purchase order.
