Thank you! Yes, that did work…after I found my true error.
My true error was I had selective access checked for the G3 Location List!
The details: I discovered this by going back to the Supply Chain Start model and creating a SYS07 test module, adding the Format and Formula one line item at time. And then repeating that in my SC model, which the CODE(ITEM('G3 Location')) formula didn’t retrieve any location data!
I hope this doesn’t happen to others yet know you’re not alone!
