Thanks, and excellent testing.
I get that those dropdowns are dynamic and thus can’t populate until a prior field has a value - like in your first example, the list of operations to choose from depends on the Job number and Asy sequence.
Has no one at Epicor ever watched really fast data entry people? I could see this causing issues for real people, and not just when “automated” with barcode scanners.
Probably some UX designer that just assumed we will all just be using a touch screen to select from that dropdown list. At least the graphic exists to show the list is updating. That was actually valuable, and not just “pretty”.
