Stock Landed Costs MRP Subcontracting

When you subcontract manufacturing, the finished product arrives in your warehouse through an incoming shipment. Normally, landed costs (like freight or customs) are applied to the manufacturing order, but that order is not visible to users. This module changes the landed cost screen so you can pick the receipt instead.

• In the Landed Cost form, the list of allowed pickings now includes receipts linked to subcontracted manufacturing orders that have a stock valuation.
• When you validate a landed cost, the system automatically adjusts which stock moves are valued: it replaces the receipt move with the related manufacturing order moves, so the cost is correctly added to the manufactured product.
• It also handles backorders from manufacturing orders: when a backorder is created, the link to the subcontracting receipt move is updated so the landed cost still applies correctly.

The module extends stock.landed.cost and mrp.production. It does not add new menus or screens; it only changes the available choices and the calculation behind the scenes. This makes landed cost accounting simpler and more accurate for subcontracted products.
