What is the function of the "Group By" field in report generation?

The "Group By" field in report generation serves the essential function of categorizing the report data for aggregation. When generating reports, users often want to summarize information in a meaningful way to facilitate analysis and understanding. The "Group By" option allows users to organize data entries based on specific attributes or categories, such as date, location, or user types. By grouping data, the report can display aggregated values—such as totals, averages, or counts—per category rather than listing individual entries. This enhances the readability of the report and allows stakeholders to glean insights quickly from summarized data.

This function is critical for performing operations like identifying trends over time or comparing performance across different segments. The ability to group and aggregate data transforms raw data points into actionable insights, making this feature a powerful tool in report generation.
