Feature Layer with calculated fields

[Bud]

In ArcGIS Online, is it possible to create a feature layer with calculated fields?

For example, if there is a CLASS field with the value 'A', is there a way to dynamically concatenate 'A' || 'B' as a CLASS_CONCAT field (value='AB')?
And then serve that up as a dynamic feature layer for integration purposes (not a one-time thing).

I'm hoping it's possible to do that without the need to import into ArcGIS Enterprise as an intermediary step.

Thanks.

Hi, I think Notebook can be used to achieve this. You would need a Python script for the operation on feature service, and then schedule that task to run on a recurring basis.
