When an ASN is queued for receipt processing at a level 2 business unit, the level 1 business unit is notified that the shipment is in process. For direct shipments, the receipt of items automatically triggers the shipment to the next level. For transshipments, receipt of items does not automatically create a shipment, and the business unit at the next level up is notified of a pending shipment.

When an ASN for a transshipment is imported, a new change management status message is queued for export up to the next business unit. The message tells the next level that a downstream shipment has been processed.

If level 2 sends an ASN, the level 2 business unit also sends a status change message to level 1 so that the level 1 business unit knows it can make no further changes to the order.

ASN Processing, Initiated at Level 3 shows the process flow for ASNs initiated at level 3.
