I have published referenced feature layers or map images to portal. When I go to Portal and view those same layers as the data owner I am not able to see the geodatabase that is the data source for those layers. My work around is to put the referenced data source information in the description. Is there a way to see what the geodatabase data source is for a referenced feature layer or map image in Portal?
If you find that there is no way to access this information currently without the time consuming task of digging through your enterprise environment, it would be a great idea to ask ESRI for this useful functionality.
