Shipment Advice Bill Auto Complete MRP

When you buy a kit (a product made of several components, defined by a phantom bill of materials), the products that actually move in and out of stock are the components, not the kit itself. The base module shipment_advice_bill_auto_complete fills in invoice lines from shipment advices, but for kits the quantities could be wrong because the product on the stock move line is a component while the purchase order line refers to the kit.

This module corrects that calculation on account.move (customer invoices, vendor bills and credit notes). It looks at the purchase order line, checks that the quantity received is based on stock moves and that there are non-cancelled moves, then finds the phantom bill of materials of the purchased product. If a kit is found, it recomputes the quantity using the kit quantities, taking into account incoming moves from suppliers and outgoing moves that are refunds.

There are no new menus, screens, buttons or reports. The change is automatic and only affects the quantity proposed when completing an invoice from shipment advice data for kit products. It is installed automatically when both the shipment advice billing module and the manufacturing/purchase link are present.
