Description
The trace requires at least one specified starting point.
Starting points can be specified using the Trace Locations pane or, if executing as part of a script, using the Add Trace Locations tool.
Review the trace type used to check the requirements.
Solution
Ensure that a valid starting point is used for the trace.
- Use the Trace Locations pane or Add Trace Locations tool.
- Ensure that the feature on which the starting point is placed is reflected in the network topology. This can be done by validating the network topology.
