How to use inventory organization(s) as validation organizations in Order Management

Hi Team - Our client has multiple manufacturing facilities under the same business unit, and they manufacture big equipment which are usually shipped at sub assembly level and then assembled at the client site. To enable shipping at sub-assembly level / L1 component level, we are using KIT items.

One of the challenge we are facing is - based on the OM profile Item validation organization, system always validates the Item structure at the item master organization level whereas for our client, the KIT item (i.e., shippable items) could change based on the manufacturing facility. This constraints the ability to have the same part behave differently for global manufacturing company.
