I can't bring a database view created using ArcGIS Desktop v10.3.1 via ArcCatalog into ArcGIS Pro. I've tried previewing the View in Catalog as well as adding it to a map in ArcGIS Pro. In both cases, it says,"Failed to add data." in Add data message window.
The View is stored in an enterprise geodatabase (10.3.1) with SQL server. Again I have no problem bringing it in to ArcGIS Desktop applications, but ArcGIS Pro 2.1 ain't havin' it.
