The requirement is I...
The requirement is I have two inventory orgs A and Inventory Org B. We have two different Order types Order Type A and Order Type B.Inventory Org A and Org B belong to the same OU.
In the sales Order when I use Transaction type A and use inventory Org A but I see the items from both inv orgs A and Inv org B. How do I see the items from Inv Org A only?
Items shown on order line
Items shown on order line depend on OM item validation org for that OU. It does not depend on what warehouse (inv) you select in the line.
So for your example if an item is available for one Inv it would be available for the other inv (as I think the item validation org is a diff Inv , may be your item master)
