Troubleshooting: When I try to edit a Transformer Unit, I get an error stating that my relationship class doesn't exist
When attempting to edit a transformer unit, you may encounter the following error:
"Relationship class between TransformerUnit and Transformer not found. Check the ArcFM Properties for the Transformer Unit Object Class"
If you are certain this class does exist, then more than likely you are missing the DistributionTransformer model name on the Transformer feature class.
