If a Geometric Network with a coordinate system that differs from Data Frame is added to ArcMap, the following error message appears:
"Could not edit the data in the folder or database you selected. Check to see that you have the appropriate permissions."
The coordinate system of the Geometric Network is different from the coordinate system of the Data Frame in ArcMap. Geometric Networks that have been projected 'on-the-fly' cannot be edited in ArcMap.
Reset the Data Frame coordinate system in ArcMap to match the Geometric Network.
