I have a hosted feature layer on ArcGIS Online representing multiple stations, each with associated receivers and antennas. The main layer is called “stations” and I have two related tables: “receivers” and “antennas.” Each station has fields for receiver and antenna serial numbers (e.g., “receiver_SN” and “antenna_SN”), and these fields link to the related tables where each record has a corresponding “SN” field.
I need the ability to only show available receivers and antennas in a dropdown when editing station attributes in Field Maps. Each item in the related tables has a “status” field set to either “available” or “in use.” In ArcGIS Enterprise, I could accomplish this with attribute rules to dynamically update the status field and filter the dropdown. However, I can’t find a similar way to dynamically update the status or filter the domains in ArcGIS Online. I essentially want a field in Field Maps that only shows serial numbers of equipment currently marked as “available” in the related table—automatically updating when the status changes.
Is there a recommended approach for replicating this type of dynamic filtering in Field Maps/AGOL without attribute rules? Are there any best practices or known workarounds for managing equipment assignment and availability in a purely AGOL environment? Any guidance would be appreciated.
