When a purchase order is received by PO number? Does the ASN get closed out automatically?

Summary:

For international purchase orders our client is creating an ASN in Oracle to prevent planning from rescheduling the purchase order. The purchase order is received in WMS and the purchase order shows that the lines are fully received and delivered. However, the PO schedules show that there are still in transit shipments. In Inventory, we are unable to see an inbound shipment for the specific ASN. What is the intended functionality, should the ASN be available to receive still or should it be closed out? Should the ASN get closed automatically and should the shipment status be changed to received
