Part 1
Track the journey before the warehouse
Goods in transit have left the supplier but are not yet available for production. The transport booking, dispatch notice, tracking reference and expected arrival date tell planners whether material is genuinely on its way. Ownership and stock accounting can change at different points depending on the agreed delivery terms; do not assume that dispatched means received.
Consider 500 units shown as shipped on Friday but not delivered until Tuesday. If the plant counts them as usable on Friday, it may promise production it cannot start. If it ignores the shipment entirely, a buyer may place a duplicate emergency order. A shared in-transit record avoids both errors.
