I have a dataset of fittings (outside the utility network) that appear to be snapped to gravity main lines that were created from the snap geoprocessing tool. When I append these features into structure junctions (fitting subtype), no vertex is created on the gravity main. If you manually create a fitting (structure junction) on the gravity main, a vertex is created on the line. I'm thinking there is some type of utility network rule that needs to be modified in order to get this to work? Any guidance would be greatly appreciated!
