Aktualisierten Wert mit vorherigem Wert vergleichen?

In Microsoft Power Automate, weiß jemand, wie man den ursprünglichen Attributwert mit dem aktuellen Attributwert vergleicht, wenn "Fetch updates, changes, or deletions from feature layer" mit einem Trigger "When a record is updated in a Feature Layer" verwendet wird?

Es sieht so aus, als ob der Parameter fieldsToCompare für extractChanges das ist, was ich brauche, aber ich kann keine Möglichkeit finden, diesen Parameter in Power Automate einzustellen. Es scheint auch, dass supportsFieldsToCompare für alle meine gehosteten feature services mit aktiviertem Change Tracking auf false gesetzt ist.

Ich möchte, dass Benutzer E-Mails erhalten, wenn sich der Status eines gemeldeten Problems geändert hat. Derzeit sende ich unterschiedliche E-Mails basierend auf dem aktuellen Status, aber die E-Mails werden auch ausgelöst, wenn Mitarbeiter Notizen zum gemeldeten Problem eingeben, obwohl sich der Status nicht geändert hat.

@Joshua-Young We currently don't support `fieldsToCompare` in Fetch updates changes and deletions action but you can use layer queries which might not exactly solve the problem you have but you can only get the changes that matches the filter.

There is always an option to use Http Request built in action instead of fetch to send the parameters you need.

We do have this enhancement in our backlog.

Editor tracking is enabled and there is no enterprise geodatabase involved with this hosted feature service. I have a support ticket open with Esri Support and they have been able to replicate that hosted feature services properly configured have the supportsFieldsToCompare set to false in at least ArcGIS Enterprise 11.4, 11.5, and 12.0. I recreated the data in an enterprise geodatabase and that got the supportsFieldsToCompare to be true, but now other extractChangesCapabilities are set to false and Extract Changes fails with an error "The field 'layers' is required" even though the URL has layers=0 set.

If support or I can figure out a way to get this to work, I will post it here.

Is editor tracking disabled on your feature layer? Also, I not certain but it might be disabled if you have a FS referencing data from enterprise geodatabase.

@AkshayHarshe thank you for the information. I tried using the "When a HTTP request is received" trigger only to find out that our instance of ArcGIS Enterprise 11.5 is hard coding all hosted feature services supportsFieldsToCompare property to false with no option to change it. So any extractChanges calls with the fieldsToCompare property fail.

Assuming that the change is already made by the time the automation is triggered (would make sense).

In this case, I would use an intermediary database with limited information. E.g., ObjectID and Status. Use Power Automate to grab the recently edited item, then compare to the secondary database to see when the Status changes, and subsequently update the Status for that item.

While a little more work, this should work well.
