Presently, the warehouse mobile device has a quantity wheel limited to 20. If item is less than 20, the wheel picks up correct quantity. But, if the item quantity is more than 20, customer has to take extra effort to go into edit mode, remove existing quantity and write new quantity. The warehouse mobile device should allow the system to by default populate the picking item quantity (in case if is >20) or permit to override the existing quantity (currently new value concatenates with the existing value).
