Hi @Robert Goff!
I solved this in a different way.
"Select Reserved ITEMS" in Inventory Usage APP works on INVRESERVE Object.
INVRESERVE object has a relationship with INVENTORY objetct called "INVENTORY". This is very important because INVENTORY has a field called CURBALTOTAL and this is what I want to use to solve this

Then, in the application editor, above INVUSAGE, I edit (in the dialog editor) "selectedreserveditems".

Open the window where I add a new column and In the attribute field, I choose INVENTORY.CURBALTOTAL

The result would be this one below

Regards!
