I am using 8.0.2 fresh install. I created two content types:
2. Inventory Item
Inventory Item has a entity reference field type which links back to Inventory. Using default settings and auto-complete this kind of works. The problem is I need the auto-complete to use the Inventory "part number and/or part name" not the title.
I created a custom view, changed it to type entity reference, selected the part number as the entity reference "style options" - hit save and the view works as expected.
