All our subcontractors don't give us pricelists for components that are purchased by them. So We only know price of production + price of components purchased by them in total. I used full BOM for the products where some of included Products(components) were dropshipped with price 0(those that were purchased by subcontractor) + some were resupplied from our stock. Eventually Odoo picked information that recently those dropshipped components were purchased with price 0 and set everywhere inside products price 0( AVCO method is used for calculation). So this fact ruined BOM overview (now estimated cost is far from reality)
How to exclude Dropshipping from counting? Because in future We have to use it again.
Big Thank you!
