Its use in the warehouse
In accounting, the stock ledger supports inventory valuation with a cost method. In the warehouse, its use is operational: it explains why today's stock is what it is. A shortage is investigated by tracing the stock ledger back to the movement that does not match physical stock.
How Chainlink WMS applies it
In Chainlink WMS, the stock ledger is consulted by product or by warehouse. Each row shows the date in the warehouse time zone, the movement type, the signed quantity, the lot and serial number, the origin and destination locations, the user and the document that originated it. Every night, Chainlink checks that the stock ledger reconciles with on-hand stock and notifies the people who manage inventory if it finds a difference.
