Hi there,
we are having some issues, possibly related to relationship classes. We use Feature Services to edit Features using WebGIS (JS API). There is one Service containing a layer based on a feature class (point features), which is in a relationship class with another feature class (polygon). It is a composite 1-M relationship, that moves the polygons, whenever the point is moved. Important to mention: The feature class is located in an enterprise GDB, based on SQL Server. We also use SQL-Triggers to automate some tasks.
That normally works fine. However, under some circumstances, the edit fails (service-response: error 500, "Unable to perform applyEdits operation."). This seems to be the case if the SQL-Trigger and the relationship class both try to edit the related features.
BUT: If we do the same edit in ArcMap using a direct GDB-Connection, there is no problem. There is also no problem if the SQL-Trigger is disabled. Only the combination triggered via a Feature Service seems to produce some kind of conflict.
I read (Prepare data to publish a feature service—ArcGIS Server | Documentation for ArcGIS Enterprise) that the related layer has to be part of the service. However, it only says "table", not "feature class". I still tried this and, surprise, it didn't help.
Any ideas on that?
