Message
Duplicate naming rule assigned to a load case.
Severity
Crucial.
Detailed Description
The name of a load case may be defined by you or generated by a naming rule. If a naming rule generates the name, only one naming rule can be assigned to the load case.
Possible Cause
Copying and pasting a load combination that has factored load cases with names derived by a naming rule can generate these duplicate naming rules. It is not likely that a load case will have a naming rule-generated name so this situation should be a rare occurrence.
Possible Impacts
The Structural Analysis task will not be affected by these additional naming rules except that the name of the load case will not be generated correctly, resulting in load cases with the same name. Warning messages will be logged to the export log if an attempt is made to export these load cases during an export model operation; hence, third-party structural analysis packages will not be able to accept two or more load cases with the same name.
What You Should Do
Run the Clean Database custom command. The naming rule will be tagged as To Be Deleted by this command. Allow the command to remove the naming rule from the database.
