The receipt process for transfer orders in the warehousing app depends of the warehouse type. When the warehouse is "warehouse management controlled" it is mandatory to receive the transfer order via a license plate. This must be the license plate of the "ship warehouse". When you receive a transfer order of a warehouse which is none warehouse management controlled, you have to receive it in the warehousing app via" transfer order item receiving" or "transfer order line receiving". Main goal should be to have one receipt process for different orders, shouldn't be difference whether it is a purchase / return or transfer order. I would suggest that it must be possible to receive transfer orders from a warehouse management controlled warehouse in the same way as a transfer order from a none warehouse management controlled warehouse.
