Hello,
When I run the OD Cost Matrix tool (or Closest Facility), there are sometime records that are on a "non-traversable network." Is there a way to return more results for those missing records? What do you do when those pop up for you? Thanks!
You will get that message if the locations (origins/destinations/facilities) are located on edges that restricted. In that case there is no path that can either start or end there.
One way to get around this is to locate on another close by edge rather than the closest restricted one. The way to do this is either bring up the OD or CF analysis layer properties, then on the Network Locations tab at the bottom, check on the option to "Exclude restricted portions of the network", and then load in the locations. The other way is to use the Add Locations GP tool to load the locations and then check on the same "Exclude restricted portions of the network".

Thanks, Jay! Sadly, neither of those suggestions worked - I really thought that would have solved the problem! Am I just out of luck since that didn't work?
How did you load in the locations after changing the exclude restricted settings? Were you loading by "network locations"? Those could be the old pre-computed locations that fell on restricted edges. You need to load by geometry.
I created a new OD Cost Matrix, then did the network settings (exclude restrictions), then loaded my locations. I used geometry, my search tolerance is 500,000 meters. Does this help?
