I am in a testing and learning mode with the Utility Network. Though there have been many bumps in the road, I continue to make (albeit slow) progress. Right now I am having issues with the Stage Utility Network tool. While this tool successfully ran in the FGDB environment, errors happen when using this tool on the exact same database, though in an enterprise environment. The first error was resolved by changing the database connection from the SDE user to a superuser (using postgres). The current error being encountered is as follows. The service area FC being used is located inside the dataset, but the same thing happens if the service area FC is located outside the dataset. Suggestions?

Also, I have been looking at videos and youtubes and written documents to understand the UN better. Any thoughts, ideas, or suggestions on good best practice info on UN would be greatly appreciated.
