Sent by suppliers or logistics providers to buyers or their designated recipients, this transaction set communicates shipment details and management information related to purchase orders. It is typically sent in response to or in reference to an existing purchase order, enabling the recipient to track and manage incoming shipments. The PRF (Purchase Order Reference) segment links the shipment to the original order, the SSD (Shipment Sort Segregate Data) segment conveys detailed shipment handling and segregation instructions, and the DTM (Date/Time Reference) segments establish critical timing information such as shipment dates and expected delivery windows.

Consider a scenario where TechSupply Inc. manufactures computer components and ships an order to ElectroRetail Corp. TechSupply sends a Purchase Order Shipment Management Document referencing the purchase order number in the PRF segment, includes special handling instructions via the H3 segment to indicate that certain components require temperature-controlled packaging, and specifies the delivery location using the N1 loop to identify ElectroRetail’s receiving warehouse. The SSD segment details how the shipment should be segregated—for example, separating standard components from expedited items—while DTM segments indicate the shipment date and expected delivery date. ElectroRetail receives this document and uses it to prepare receiving operations, allocate warehouse space, and alert the appropriate departments about incoming materials requiring special handling.
