We are using a multi-company setup, where products and customers are shared between companies. We need this, because the companies are in different countries and have separate accounting.

We buy parts, and assemble them into products that we sell to our customers. We would like to use Odoo's manufacturing and inventory modules to do this.  

The problem we are running into is that Bills of Materials are not shared between companies, so we need to maintain separate records of BoM's for each company. This seems wrong and error-prone, since all the products are the same and have the same BoM's. It also just gives a lot of work with maintaining them.

We discovered today that if you log in as a super-user in Odoo 12, you can actually see the BoM's for the products, even though the BoM's are defined/belong to another company, and you can complete a manufacturing order using those BoM's. This makes it seem like it is a permissioning issue, but we have not been able to find any permissions that guide this. 

So - does anybody know how we solve this? - Is there a way we can share BoM's between companies for products that are already shared?
