Hi Jaideep,

thanks a lot for your reply!

I noticed afterwards that my conclusion, the problem corresponds with BoMs was wrong (it was just a coincidence in that case).

The root of the problem were reservations for multiple MOs on the components. 

Still, I don't get why odoo chooses the subordinated location for every process, that is not exactly in line. 

Example 1: I validated a delivery from a vendor. The ordered quantity was 5000, the delivered quantity was 5092. I have configurated a putaway rule for the warehouse and all the location. Odoo puts 5000 units in the correct location, but puts 92 units into the subordinated one which should always be empty.

Example 2: Odoo allows negative stock, which I already found out is not possible to change in the online-version. Instead of creating a negative stock in the correct component location (which would be acceptable), it creates a negative stock in the subordinated location which should always be empty.

It is possible to keep track about the correct stock, but we have to check the movements and locations of every record that is created before validation which is pretty annoying.

Does anyone has a similar issue and a possible solution to this?

Thanks in advance :) 

Maybe you could have a putaway rule defined for components that are manufactured (having a BoM).

You mention it works for components that aren't manufactured (not having BoM), a correlation here could be that manufactured components have a default location of WH/Stock set on manufacturing operation.

This is a suggestion, I haven't tested.

There are a few other ways as well (tried and tested) 

1.select component and finished product location in Miscellaneous tab on MO prior to confirmation 

2. use 2 step manufacturing route so components are picked from correct locations and moved to pre-production area

3. Have more than 1 manufacturing operations which can be selected on Miscellaneous tab, 

4. make visible and selectable the 'from location' field on the component lines of an MO
