Hello,
I've followed the documentation for creating a Survey123 survey using an existing feature service (https://community.esri.com/groups/survey123/blog/2017/09/25/working-with-existing-feature-services-in-survey123-for-arcgis ) and am having two main issues. I am unable to see the data collected in the survey in the SQL enterprise database and I am also unable to get the photo attachments collected in the survey in the child table to appear.
My general work flow was as follows:
- Created two layers which have a one to many relationship which is using the parent global ID as a foreign key in the child table
- Enabled archiving on both tables and enabled attachments on the child table
- Published layers as a service with feature access and sync enabled
- Added the feature service as an item to our companies ArcGIS online account
- Created a new survey in Survey123 Connect version 3.0.127 using the existing feature service
- Published and collected sample data
I am using the following:
- ArcMap 10.5.1
- ArcGIS for Server 10.3.1
- SQL Server 2012
- Survey123 Connect 3.0.127
- Survey123 for Android 3.1.68
Any tips would be greatly appreciated! Thanks for your time 
Emily
