Orders with Maximum or Over Capacity with less capacity vehicles

Hi all,

How will the Jsprit engine treat order with quantity equal to max capacity of vehicle type or more than that? Will it automatically know to send this vehicle to fulfill less than what is order demand in first go then remaining part after that?

How about order with over capacity? I see, jobs will be unassigned due to over limit. Then when we split it to multiple small orders with each small one be full capacity of vehicle types, what will happen? Then may be this problem can be solved.
Anybody solve this problem before then please share your approach?
