Cause
In the project, a topology interruption point has the same DT as a "normal" interruption point.
Solution
- Locate the topology interruption point in the routing path network by using the Go to (graphic) functionality from the popup menu in the Message management dialog.
- Call up the Properties <...> dialog of the topology interruption point, and enter a DT not yet assigned in the project into the Displayed DT field.
- If required, start a new check run.
