Dear Odoo'ers 

I would like to set up a process that when I confirm a Purchase order, odoo automatically manufactures the products (so raw materials will be deducted, and ready product will be added). All BOM's are set up. 

Up until now, I have tried multiple subcontracting routes, but they did work work. Also tried MTO, but that only triggers with a Sales order. 

Is there somebody that could help me? 

Cheers!
