A warehouse shipping order (940) is a document that instructs a warehouse to pick, pack, and ship products to specified destinations. The warehouse or distribution center receives this transaction set from a supplier, manufacturer, or their logistics partner, typically in response to a purchase order or as part of a planned replenishment cycle. The transaction set uses the W05 segment to establish the shipping order identification and references, the W01 segment to detail individual line items with warehouse-specific information such as item numbers and quantities, and the N1 segment to identify key parties involved such as the shipper, receiver, and bill-to entities.

Consider a scenario where TechCorp Manufacturing sends a 940 to National Logistics Warehouse to fulfill holiday season demand. The warehouse receives the transaction set containing multiple line items—for instance, 500 units of model ABC-123 destined for RetailChain’s distribution center in Atlanta and 300 units of model XYZ-789 destined for a RetailChain facility in Denver. The W01 segments specify picking locations within the warehouse, requested ship dates, and special handling instructions. The 940 includes hazardous material information via LH1 and LH2 segments where applicable (such as batteries or electronics requiring special packaging). Once the warehouse processes and ships the order, they confirm execution through a corresponding transaction set, closing out the shipping order.
