What is a report definition in Pega?

A report definition in Pega serves as a fundamental construct that outlines how data is to be retrieved and displayed within reports. This rule enables developers to specify the data source, the columns to include, any sorting or filtering criteria, and other relevant parameters that dictate the content and structure of the report.

By accurately defining these elements, users can generate reports that effectively present the information they need, helping them make informed decisions based on the insights derived from the data.

The other options, while related to reporting, do not precisely capture the essence of what a report definition is. A summary of case statistics and performance pertains to the outputs one might achieve with a report but does not define how that data is organized or presented. Guidelines for report formatting focus on aesthetics rather than the rules governing data retrieval, and a script for creating unlimited reports suggests automation that is not inherent to the concept of a report definition itself. Thus, the emphasis on data retrieval and representation makes the first choice the correct answer.
