Field Calculation

Since version: 1.5

With the Field Calculation profile, expressions can be written to update a field value based on expression logic. This profile is used in field calculation tools in ArcGIS Pro, ArcGIS Enterprise, and ArcGIS Online. When the script is evaluated, the return value is cast to the field type of the output value. It is best practice to handle casting within the script for full control of casting behavior to Number, Date, or Text return types.


The following products implement this profile:

Spatial reference

The spatial reference of the expression's data source1 determines the execution context's spatial reference.

Time zone

The time zone of the expression's data source1 determines the execution context's default time zone.
