I have a feature layer created from users collecting data using Survey123. I add this layer into ArcGIS pro and use various other layers to select by location in Pro.
Is there a way to have this selection set show up in the Survey123 web app as the selected records and use the report template there?
Feature selection is a temporary state specific to a single application. There's no way a feature selection in Pro could be recognized in another application without some kind of script running between the two.
If you want to generate reports from within Pro, you could probably do that using Python and the arcgis and requests modules.
Generating S213 Feature Reports from ArcPro is a cool idea. If anyone has done that, I'd also be interested. Next, I just need to convince my company to get me ArcPro...
But ya, as far as I am aware, you'd need to recreate the query within the S123 website.
