The Column Chooser dialog box is used to select the columns of data that are displayed in the report for grouping and sorting the data. The columns available in the Column Chooser dialog box are determined by the display columns configured for the data provider associated with the report.
When you open a report, the Column Chooser dialog box is displayed if no columns have been previously selected for the report. To open the Column Choose r dialog box, right-click at the top of the report in the columns panel and select Column Chooser.
