A question regarding an error message

[AnarJofaryv]

Hi,
I am running the VRP problem from for the file offered on the on-oline training vourse offered through ESRI. I keep getting the following message:

Warning: Impedance attribute is not time-based.
Error: Invalid context.

I redid the problem several times and each time I got the same message. Could you please help me out? Thanks.

How do you create the VRP layer? Also, if you bring up the properties of the VRP layer what is the impedance attribute set to?

I guess your Time Attribute in Layer Properties (Analysis Settings tab) is set to empty. If that's the case, please select a time attribute from the drop-down list.

Thanks.
