Orders with max or over capacity

Hi all,

How will the engine treat order with quantity equal to max capacity of vehicle type ? Will it automatically know to send this vehicle back to base for next job ?
How about order with over capacity ? I guess this job 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?
Anybody solve this problem before ?

Than,s
