As I know there is no such thing as a Sub Advanced Inventory plan. Open the sample file again and hit CTRL 1 keys. Make sure you have Enterprise Platinum edition as I mentioned earlier.

According to Tori B above I don't need Advanced Inventory so I shouldn't need the platinum edition to run EIR

To answer your question, no, you do not need to have Advanced Inventory enabled to turn on Enhanced Inventory Receiving (EIR) in QuickBooks Desktop. EIR is a separate feature that can be enabled independently of Advanced Inventory. If you need some help activating the feature, follow the steps I'm including below.
