Hello Alessandro,
There is an Mobile Device Menu Item for mode=work that is called 'Warehouse Transfer' that does just that.
To support that menu, you will need to configure a 'Default Warehouse transfer journal' in Warehouse Management Parameters in the 'Mobile Device' FastTab. I think Worker needs to have access to the destination warehouse as well (can't remember for sure)
To start, you scan the starting location or LP (if used), item quantity etc, Next you scan the Warehouse and destination location.
Kind regards,
Danny
