I set up my collaboration this way without realizing that it would do that. Now I can no longer delete the version of the data that the service was published with as part of our reconciliation and post process. Is this intended or a bug? I don't understand why a replica is needed to make a copy of the layer to arcgis online.  ... View more

I am working on a dashboard that will keep track of hydrant inspections. I have a few indicators set up that track the number of repairs needed, missing reflectors, etc.... I have set up a date selector, and this filters the data properly whenever I change the date range. Now, I would like to set it up so that when I select a hydrant inspection zone in the map, it shows me the updated statistics for that particular zone. So far, however, I can't get it to work.  I have gone to the map settings > Layer Actions > Fire Hydrants and set up the indicator with a spatial filter.   But when I select the zone on the map, the count changes to 0, even though there are matching records for the indicator in that zone. What am I missing?   ... View more

I am pretty new to using Portal, so forgive me if this is a dumb question. I have published our parcel fabric as a referenced feature service. That being said, on occasion, I want to use parcels in other maps without having to worry about the end user being able to edit the data. I would love to be able to create a "View" of the feature service, but that can only be done if it were shared as a copy. So, what is the best workflow here? The only alternative I see is to publish a second copy of the parcel fabric as a copy, but now we have a second version of the layer that does not stay synchronized with the source data, which just adds to the administrative headache on my end. What am I missing here? ... View more

Not a question, but just wanted to share a script that has been helpful for us. In the past we attempted to use this incredible script created by @jcarlson to scan our organization to figure out where feature layers were being used. The script is amazing and worked for many people, but not for us. It ran, and appeared to be working, but after a few seconds, it would hang and then never complete. It took us a long time to figure out why, but we finally did.  We had some old App Studio applications in our ArcGIS Online organization. These are classified as "Native Applications," which get lumped in with the scripts scan of all applications in the organization. Once we added a debug function to list the layer being scanned, we found that it was getting hung on those native applications every time. We had to add in a segment to skip that application type, but once we did, it worked flawlessly. Here is our full code, which will skip Native Application item types if they are causing issues for you. """ Script to find where a specific AGOL layer is used within an ArcGIS Online organization.
