I am trying to Solve best routes between each OD (origin-destination) pair. I want the route "Name" field to be populated by the value in the field "PRMT_ID" of the origins. PRMT_ID field is in the destination point feature also.I am using python code as below: The route solution works fine, except that the "Name" field of the route only says Location 1-Location 2. It doesn't populate it with the value in the "PRMT_ID" field as I was expecting. I wonder if anyone can advise on how to make the route layer show the "PRMT_ID" value instead of saying generic Location 1-Location 2
Appreciate any help!
I wrote the code referring to the MakeRouteLayer example 4.
and below are a few lines
fieldMappings = arcpy.na.NAClassFieldMappings(outNALayer, stopsLayerName)
fieldMappings["Name"].mappedFieldName = "PRMT_ID"
arcpy.na.AddLocations(outNALayer, stopsLayerName, inOrigins, fieldMappings,"")
arcpy.na.AddLocations(outNALayer, stopsLayerName, inDestinations, fieldMappings,"")
