Hi Giulio, You can use the "supplies wood Y" as a BOM (Manufacturing Bill of Materials). It depends on how much quantity of BOM's use to Manufacturing the X product as well as use the Production Run between the time of Manufacturing the X product (finished good). It's depend on the status of Production Run. -> If BOM not available in a stock Production run in creating status. -> If BOM available in stock Production run in process status. -> The production run is closed after X product (finished good) is ready. The total cost of Manufacturing the X product is based on Unit Cost of BOM 'S and quantity to be used for Manufactured the X product.
Thanks & Regards, Karam
