Assuming you have access to the Network Analyst extension that Dan has linked, you setup your Start and Finish points with Route Names. You need a start point to go with each corresponding finish point. Think of it like this - if you have Point A and you want to calculate routes to Points M, N & O, you need 3 copies of Point A, each with a unique Route Name that is also referenced by each finish point (i.e. Route A-M, A-N & A-O). When you run the Solve tool to calculate routes, it recognises those route names and calcs the route from A to N, then another for A-M and again for A-O. The same dataset could also then contain start points B, C, etc and other finish points, and as long as you have those start points copied and named to match each required finish location, it will only calculate those routes. It seems like a simple concept, but it took me a while to figure this out so, thought I'd share it.  Below is an extract from a python code that generates the Start and Finish points based on 2 input datasets (the start points actually being polygons so you can see the dissolve and conversion steps added in to deal with this). The code goes on to solve the network too, but I haven't added that as I haven't got it running properly in an automated manner (which is how it is supposed to run). I have a model that does this too for users to use in ArcGIS Pro (what I used to build the below code in the first place).    # Variables - update these lines SDPRoutes = "Output feature service" # ArcGIS Online feature service containing routes to be updated origins = r"\\path\to\input\origin\features" #
