R12 How To Use One Item Master Across Operating Units ?

Hello :

I have found the following note about R11, However I was wondering if it is the same work around for R12.

How To Use One Item Master Across Operating Units - Business Groups - In Oracle Purchasing? (Doc ID 1310609.1).

I think the approach will be to create a new Child Inventory Org that points to US Master Item.

Please Advise

Example.
US1 Operating Unit
- USM is the Item Master Inventory Organization
- USM has US1 Operating Unit in the account information setups
- US1 has USM as the inventory organization in the Financial Options

US2 Operating Unit:
- US2I - Inventory Organization created in US2 OPerating Unit
