Which functionality is associated with the Pivot On field in a report?

The functionality associated with the Pivot On field in a report is to define the vertical axis of the report. In reporting and data analysis, especially in pivot tables, the vertical axis typically represents the categories or dimensions being analyzed. By selecting the Pivot On field, you can organize and group the data accordingly, allowing for a more structured view and analysis of the information being presented. This allows users to effectively interpret trends, make comparisons, and derive insights from the data.

The other functionalities mentioned in the options do not relate directly to the role of the Pivot On field. Exporting data, deleting data, and displaying user totals represent different functions in data handling and reporting. Each of these actions is distinct from the purpose of defining the structure of how data is presented in the report.
