Is it possible to share, what are the content your client is expecting on the pallet label
if you are planning to take a printout of label using the TR information then you won't be having the Pallet number(Storage Unit number) and source or destination storage type also the pallet qty(LE qty) from the WM2 view (can be achieved via custom code but if you have more then one value defined in the WM2 view then you need to apply some logic which value system should pick)
