We would like to use a Feature Service for a web application and want to show SHAPE.LEN and SHAPE.AREA fields in the pop-up. However, these fields are missing from the Feature Service. They show up in a Map Service, but not an ArcGIS for Server Feature Service. These would be helpful. And no, I shouldn't have to add a new field and calculate the length of a line or area of a polygon. This is redundant and a waste of time and resources.
This Idea was implemented with ArcGIS Enterprise 10.7. Please see the following documentation for more information: What's new in the ArcGIS Enterprise 10.7 portal—Portal for ArcGIS (10.7) | ArcGIS Enterprise
