In our company we fabricate products that use metal tube. A typical manufactured product in our company uses a mix of components stocked in our warehouse, and some custom components only used for that product. We manufacture the products only when the customer places an order.

We're attempting to use the MTO route, however even if some of the components are in stock in Odoo, Odoo still generates a new purchase order for every component on the bill of material.

Is there a way to set up a automatic workflow where Odoo checks for stock on components before generating a new supplier purchase order? 

Thanks,
