Arcpy Network Analyst Solve Failure

JoeJung

While using the Network Analyst Closest Facility task in a python script, my solve operation is failing on incidents that have been located on disconnected network segments.  I have tried to use:

arcpy.Solve_na(cf_layer, terminate_on_solve_error=False, ignore_invalids=True)

but then the routes feature is never populated with any data at all, even for incidents that do have a solution.

When I run this same operation in ArcMap, solve executes properly with the addition of a warning window displaying the incidents solve was not able to find a solution for.

This brings me to my question:

1. Is there a way in python for solve to complete on all other features that do have a valid solution so I can continue with my analysis?  If not,  am I able to access the Network Analyst warning window within python so I can filter out incidents I know will fail?

Thanks in advance,

Joe

For anyone else experiencing something similar,

It turns out that by deleting and recreating the network dataset, all of the operations began to function as expected.
