Hello,

In Odoo 16, I have configured some of my products to have “MTO” and “Buy” operations. 

It seems to work well in principle: I create a customer quote, as soon as I confirm it, a supplier quote is created with the items to be ordered. Receipt and delivery pickings are also generated. 

I'm having a bit of trouble understanding how it really works and how to configure operations and routes correctly, because I can't get it to work as I'd like.

Let's say I already have 35 copies of a product in stock. If I create a sales quotation to sell 40 to a customer, a purchase order to the supplier will be created with quantity 40.

I would like only 5 copies to be ordered, and the 35 already in stock to be included in the quote.

Is this possible? Is it just a matter of configuration? 

Thanks in advance,

Mélanie
