Reservation for project stock and plant stock

Hi there,

Here is the scenario we would like to reach:

We use project stock for our components, but sometimes, we get available plant stock for those components (for instance an old project with some rests, that we then put in plant stock).

When running a reservation for a component, what we would like is the system to check first if there is project stock for this component, and then if there is plant stock for this component.

It is not easy to check humanly for all the components we supply as they are numerous.

Is it possible?

Additionnal remarks: we use non valuated project stock.

We are on ECC 6.0.

Thank you for your help!

Claire.
