Description
To work with a utility network or trace network in an enterprise geodatabase, the portal account must be assigned either the ArcGIS Utility Network user type extension or the ArcGIS Trace Network user type extension.
In ArcGIS Enterprise 11.1 and earlier, the ArcGIS Utility Network, ArcGIS Trace Network, and ArcGIS Parcel Fabric user type extensions were separate. Beginning with ArcGIS Enterprise 11.2, these are now consolidated into the ArcGIS Advanced Editing user type extension.
Solution
Have your ArcGIS Enterprise portal administrator review the license for the current user account. Changes will need to be made to the user type, or an add-on license can be configured.
