I am using ArcGIS Field Maps in my 10.9.1 Enterprise environment. I've created a web may with reference feature layers from my ArcGIS Server (not hosted feature layers in portal). The web map contain a feature layer that has a related table which is being used as an inspection form in ArcGIS Field Maps. In order to allow the field users to access and create new entry in the related table, both the related table and the associate feature layer had to be publish with editing capability ( add, update and deleting feature). In my case I also needed the field user to edit the attribute table of the associate feature, but not the geometry.
The issue I am confronted with is that I would like the field user to be able to create new entries in the related table, which is my inspection form and also be able to update the associated feature layer's attribute table. This could only be done it seems like by publishing the related table and the associated feature layer with add, update and deleting feature editing capability. Publishing with "Update features only" will not allow the field user in ArcGIS Field Maps to create a new entry in the related table. However, I don't want the field user to accidently delete any geometry from the associated feature layer.
I would be very grateful if anyone could offer a work around, any documentation or suggestion that may lead to a solution.
