I have a feature layer data set that captures records from a Survey. There are hundreds of fire station locations that are static. There are many records for a single station location (ex: each fire station submits an update every day or so-- the updates may not be regular. One station may report daily, another may report weekly).
We are trying to create a web-app or dashboard that uses the data ONLY for the most recent record submitted by each location (bonus if it will automatically re-query & update according to a specified schedule). Using 'filter by today' will not work because an update for a station may have happened a week ago, and I still need to show the information for that record along with a station that updated this morning. I'm looking for help on a solution to show: 'for each individual station, select the most recent record from MAX DATE and use fields from that record for that station in the web-app (or dashboard)'....
For example: from the screen capture, I'd like to display only specific attributes from the 4/2/2020 12:00 AM record in the dashboard/web-app. When that station reports their information again, I'd like the web-app/dashboard to automatically reflect that update...
Any Ideas for a newbie to this side of things???!!! I've been looking into ARCADE, but not sure exactly how to make it work correctly. TIA

There are a couple of comments at the following thread that may be helpful to you. They were talking about using related tables and how to set them up for updated records.
Hey Everyone,
I think I have figured out a workaround for this issue! Hopefully this method can help you out too.
My Method:
1a) Created a view in SDE for my related table, where the SQL expression specifies only the most recent related record should be returned if there are matching global ID's in the related table (ie. if there are more than one related records for a single feature). My expression input into "Create Database View" tool:
