Dear all,

we're a small company that makes measurement equipment and I work on Odoo integration in our processes to make everything much more optimized and transparent.

Due to the size of the company some of technological operations are given to our partners-subcontractors.

Let's talk about product A, that consists of:

* product B - 1 pc

* product C - 1 pc

   |---- product C.1 - 1 pc

   |---- product C.2 - 1pc

   |---- service that is acquired from subcontractor

* product D - 1 pc

During one bright morning we've got a phone call from the client - they've requested 10 devices. Our warehouse had all raw materials including: B, C.1, C.2, D, but had no assembled C products. When I filled in and right after confirming manufacturing order to produce 10 devices I expected to see "nested" automatically created manufacturing order to produce C parts but nothing occured. Part C has its own BOM and can be ordered manually without any problem.

The same story occurs when some parts are not in the warehouse and are supposed to be purchased. Odoo, as far as I get it, checks availability of the BOM items but doesn't generate a purchase order. 

I've looked into the Odoo tutorials on Youtube - really good videos and googled a lot, but still no luck. Could you kick me in the right direction to make the supply chain process a lot more automated.
