We have a problem with Vehicle Routing Problem solver service. When the work orders from one day get submitted to be routed, there is always a remainder of tasks that do not get associated with a route. Is there a way (parameter) to force solving all the delivery tasks for each day?
There is a max Orders field in the routes which might have a default value limiting the stops per route to this value.
Another posibility woudl be that your destinations are too far away from teh network datasets edges.
