I'm guessing this is a permissions error. But everything I've tried enabling hasn't fixed the problem. Does anyone know why this is greyed out or how to fix it?

This is in ArcCatalog.

Options Greyed Out for Any Chosen Representation

  • Are you in sde geodatabse? Maybe a lock? try remove all users and connect with the owner of this table. Or view permissions in folder where the geodatabase is.

  • What user are you connecting as? Do you have DBO privilege? Only an owner can edit feature class properties.

1 Answer 1


For me, this was caused by a schema lock (as suggested by Kirtep). I had edited the RuleID field separately in Python with an update cursor. Once I closed the Python window, I could edit the Representations again. So I suspect the feature class was used somewhere else (e.g., another application, another user), and had an active lock on it.
