Component supply

A planned purchase does not become available stock. Warehouse Operator records the arrival and a separate acceptance confirms the quantity and evidence. A receipt may be partly accepted while the remainder stays pending or rejected. The related stock event records the posted inventory effect. Purchasing Manager can compare the accepted scope against the order and supplier bill without changing the receipt history.

For a kit build, component needs are frozen as work order materials. They carry required, issued, returned and consumed quantities. A reservation claims eligible position and layer quantity for a particular work order material. Available quantity reflects existing claims, so two builds cannot both plan to consume the same units. Lot tracking retains the identity needed for a component that must be traced through issue.

• Supply. Purchase order lines establish commercial quantity and the receiving location.
• Stock. Receipt acceptance and stock events establish usable on-hand positions and their value lineage.
• Build claims. Reservations and work order materials show how much of each component is required and actually issued.

Choose receiving, held, production and storage locations within each warehouse. Agree how partial supplier arrivals are reviewed and who can confirm accepted quantities. Check that buy units convert correctly to the base units used by kit bills. A box of components should not be treated as a single component merely because the supplier invoice says one box.

Warehouse Manager should decide when a reservation becomes a firm claim and how unused material returns to available stock. Confirm the stock identity that matters for each item, especially lot number. The organization and warehouse must agree across the receipt, position, reservation and build. Purchasing Manager should prepare a supplier shortfall case before go-live.

Start with a released build requiring more labels than are currently available. Create a purchase order for the missing pack quantity, receive only part of it, and accept only the portion that passed the warehouse check. Review the resulting stock position and layer. Reserve the quantity needed for one build, then try a second build whose demand would exceed the remainder. The second claim should wait for more accepted supply. Issue actual units to the first build, return any unused units and compare required, issued, returned and consumed amounts.

• Component reservations — Open claims by stock position and work order material.
• Receipts awaiting review — Arrivals whose accepted scope still needs a decision.
• Components in production — Stock already in production custody, separate from available warehouse stock.
