Additional Information
This is supported through arcpy.nax API (refer to this documentation: https://pro.arcgis.com/en/pro-app/latest/arcpy/network-analyst/what-is-the-network-analyst-module.htm for more information), but not through arcpy.na API yet. To use arcpy.nax API for this workflow, refer to the following: ```python import arcpy # Initialize solver object using current active portal as network data source. portal_url = arcpy.GetActivePortalURL() service_area = arcpy.nax.Route(portal_url) # Additional logic to load inputs, set analysis settings, solve, work with result, etc. # It is the same workflow as if you were working with local network dataset. # Follow documentation here, https://pro.arcgis.com/en/pro-app/latest/arcpy/network-analyst/servicearea.htm ``` Script tool written using arcpy.nax API can be published as web tool in the portal that configured with routing services, and the web tool is able to consume routing services on the portal when running.Workaround
- Enable built-in users.
- Use a local network dataset as the network data source input instead of a routing service configured in ArcGIS Enterprise.
