We have Following Org Structures.

1 Ledger

1 Legal Entity

1 Business Unit

4 Inventory Organizations

1 Cost Organizations

We assigned all 4 Inventory orgs to this single Cost Org. Now we would like to remove 1 inventory org from old Cost Org & want to assign it to newly created Cost Org.

This way Old Cost Org will have only 3 inventory Orgs and 1 Inventory Org will be assigned to new Cost Org.

I have end dated this moving inventory org which was assigned to Old Cost Org, now trying to assign to new cost org but not getting this Inventory Org in LOV.
