Query - Item Grouping Behaviour - Definition and Reference Org

Content

Hi

I'm using Release 19A.  We are currently using Procurement module i.e. Self Service procurement  (Smart forms to raise Requsitions). We are not using Inventory and we do not have Items. 

We define the Functional Area Catalog (Purchasing) and will assign the leaf level category(Purchasing Category) to the Catalog.

I had a query on the Inventory Org setup.

1) Manage Item Organisation (task) -  I have defined a Master Org (Item Grouping = 'Definition Org')

2) We have multiple Inventory Orgs under the BU. So when I define the Inventory Org (Item grouping is defaulted to 'Reference Org') and when I save the data I get a message saying "Do you want to assign all Items in the Definition Org to the Reference Org.
