Its use in the warehouse
Each company in the supply chain is responsible for one step back and one step forward. In the warehouse, traceability is built by recording the lot or serial number at every receipt, movement and shipment; a single step without that data breaks the chain. It is the foundation of a product recall: identifying quickly where a lot is and which customers received it.
How Chainlink WMS applies it
In Chainlink WMS, the lot and the expiration date are captured at receiving, including from GS1-128 labels; picking confirms the lot with a scan, and the stock ledger filtered by lot or serial number shows each movement with its date, locations, user and document, including the outbound documents with their customer.
