Its use in the warehouse
With an LPN, the warehouse moves the complete unit instead of item by item: one scan of the code puts away, transfers or picks all of its contents. The contents remain recorded by product, lot and serial number, so inventory does not change when the unit is built or broken down.
How Chainlink WMS applies it
In Chainlink WMS, pallets are built at receiving: each read is added to the open pallet until it is closed and its label is printed with the code in Code 128. When receiving is complete, each pallet receives its own put-away task. At picking, a pallet is taken whole only if all of its contents belong to the order.
