I am trying to solve a vehicle routing problem and the Network Analyst shows two errors.
Error: "Failure while working with internal route problem instance"
Error: "A column was specified that does not exist."
After clicking solve the algorithm runs well. I have outputs in route properties, but there is no route on the map. I can see only the sequence of orders.
I found this thread here:
And If I set the output shape to None, no error appears but still cannot see the route (only for "straight line" it connects the nodes according the sequence, but that has nothing to do with road network). In the attribute table there is "OK" for all fields in "Status" column and "Null" for all "ViolatedConstrains".
I am using Desktop Arc GIS 10.1
I welcome any help, recommendations or tips what to do or what these errors could mean.
Do you mind elaborating on the solution to this error a little more? I am having a similar error come up. The orders are being assigned sequences but I need the route geometry to be made.
Which name in your cost attributes had an error?
