License plate inventory management lets you define any type of packaging unit—boxes, cases, or pallets, for example—and any number of packaging levels. Default packaging structures, in use when you receive product, can be defined per item, origin, or destination. You can assign label formats by packaging type, origin, or destination to use when printing labels. License plating lets you attach label IDs to packs, which become the identifier for your product/package. The license plate lets material handlers move inventory more efficiently by using the license plate ID. This, in turn, moves the entire content of a package. License plating is required for companies that require their units to be serialized.
