How is a 'Calculated Field' created in a ServiceNow report?

A 'Calculated Field' in a ServiceNow report is created by using formulas in the report configuration. This functionality allows users to define new fields that aren't directly available in the existing data set by applying calculations or transformations to the data within the report. For instance, a user could combine values from existing fields, perform mathematical operations, or manipulate data to derive new insights directly within the report.

When using the report configuration, users can specify the formula they want to apply, which might include functions like sum, average, or other mathematical operations. This capability makes it possible to generate dynamic data views and insights tailored to specific reporting needs without needing to alter the underlying database structure or create new database fields.

While the other options describe various data handling or reporting mechanisms, they do not align with the specific process of creating a calculated field in ServiceNow. The emphasis is on the use of formulas, which distinguishes this method from simply selecting existing fields, compiling data from multiple reports, or manually inputting data.
