I tried to create a model for vehicle routing problem in modelbuilder and I get some errors when it runs, errors concerning the routes. I have some stores and one depot. When you add 'Add location' it asks for the input of the network analyst layer, sublayer and input locations. For the depot and the stores i can input the right location because they have feature data layers but the routes doesn't have a feature data layer (routes being created just in vehicle routing problem analysis). My model looks something like: Make New Vehicle routing problem (Streets_ND) -> Add location (orders) -> Add location (depot) -> Add location (Routes) -> Solve. Any ideas?
Thanks, Andrei Astilean
