Cause
|
May occur if a Demand Diagram has been imported from an external source and the import file contains duplicate demand category names:
- Demand categories in the file used for import have been defined with the same name.
- On import to a Demand Diagram, the demand categories with duplicate names are renamed by InfoWorks to generate unique names
