Shortest Distance processing stops with the following error message:
Invalid syntax for specifying panel sorting order.
The format of the wiring rules XML file being used is incorrect. This is usually because a wiring rules file from legacy promis.e (prior to promis.e 2007) is being used.
Ensure the appropriate, updated wiring rules file is specified on Run Shortest Distance > Setup > [Wiring Rule Version] Configure > Wiring Rule File
Check the contents of the wiring rules file for errors.
If the wiring rules file from legacy promis.e has never been updated to the new format, contact Bentley technical support.
