The Enterprise 21 ERP system supports the use of pallet ID’s or license plates throughout the system’s warehouse management and inventory management processes. License plates can be used to identify single-product or mixed-product pallets in standard or random-pack quantities. Enterprise 21 also supports infinite-level nested license plates, which are license plates within license plates. Nested license plates can be used for creating consolidated truckload shipments where the nested license plate houses the complete shipment data and can be sent via advance shipping notification (ASN).
