IV. SPECIFIC BEHAVIORS
- The WMS order ID is sent in Warehouse Shipment Order #.
- The WMS order number is sent as the shipment reference ExternalOrderNumber.
- The same reference behavior applies to Purchase Orders and Receipts.
- OrderSource behavior: WMS123 uses TechOMS as the default OrderSource value when sending shipments and receipts.NOTE : The OrderSource value can be overridden through Reference Mappings. When an override is used, techOMS sends the mapped value to WMS123 and saves the actual value sent as an OrderSource reference.
WARNING : If the mapped OrderSource value is empty, techOMS logs a warning and sends the default TechOMS value instead.
