Dynamically Populate a Domain/Dropdown Based on Unique Values In Different Layer

[AKRRMapGuy]

We have 2 referenced Feature Layers/Tables. One is a Point Feature Class that has points with unique IDs on them in a text field. The other is for use in the field using Field Maps.

We are in need of a way to populate the dropdown/domain on the ID field of the table in Field Maps with the Unique IDs from the point Feature Class. I am trying to find a way so that users don't have to free type the IDs in the form in Field Maps.

Is there a way to do this with Arcade?

Hi @AKRRMapGuy 

If you set a relationship between the Point Layer and the Table based on the unique id (1:1 or 1:M), the ID from the origin table (Point Layer) is automatically added to the destination table (Table). No need for Arcade.

I hope that helps,

Oh! It's been a couple of years since I tried that. Does this also work on referenced Feature Classes, not just Hosted? When did ESRI add that feature to Field Maps?! That is totally awesome! I will try it. Thanks a ton!

To be honest, I'm not sure. I know there was a limitation in Enterprise 11.1 with relationships that have since been rectified in 11.3. I'm hoping your trial is fruitful. Please let us know the outcome.
