Transfer order confirmation - pallet split

Hello Gurus,

Our Pallet qty is 120 cases for a material, hence one storage unit is created for 120 cases.

We have a scenerio that some customers want that pallet to be reduced to half (60 per pallets) and other customers want it like 40 cases per pallet.

During the transfer order creation, system is picking only one storage unit for 120 cases. How can i split this into 2 or 3 pallets based on customers.

I could do this by adding more handling units in LH01 and assigning the same during LT12. But want to automate this functionality.

Your help would be much appreciated.

Thanks,

Sakthi
