Inventory Organization, RMA Receiving Organization and Ship From Organization

Hi Gurus,

When using defaulting rules in Depot Repair, there are three attributes related with Organizations available - Inventory Organization, RMA Receiving Organization and Ship From Organization. Though the last two are self-explanatory, what is the first one used for? Is it for defaulting the Repair organization when using a WIP mode?

We have a requirement, where the repair organizations are different based on Item. So I defined two defaulting rules as below -

Attribute (Inventory Organization) = M1 when Repair Order Item = A

Attribute (Inventory Organization) = M2 when Repair Order Item = B

However it kept on defaulting some other repair organization when I clicked on Create Job button on Depot Workbench. Any clues on what may be missing?
