You didn't answer the question. Is your warehouse HU managed? I will assume it is....
As a rule, the handheld guy will NEVER create a TO. He is a drone, he follows orders, he doesn't think. So his work will be to open a TO on the handheld, go the origin, scan the barcode of the pallet, go to the destination, scan the destination storage bin barcode.
How is the TO created? You didn't provide any context as to why the pallet is being moved, so you must want me to guess.
