The Grouping pane allows you to configure Grouping rules, which determine how rows will be segmented in the report. You can configure multiple grouping rules, which are applied in sequence to create nested groups (e.g. group by this and then by that). If one or more configured column has the aggregation setting enabled, a summary row will be displayed for at each grouping level.
Adding a grouping rule
To add a new grouping rule to the report, select the field you wish to group by from the selection box and then click the plus icon.
Removing a grouping rule
To remove an existing grouping rule from the report, click the trash icon beside the grouping rule you wish to remove.
Reordering grouping rules
Grouping rules are applied in sequence starting from the top of the configured grouping rules list. To change the order in which grouping rules are applied, reorder the list. Clicking the up arrow icon moves a grouping rule up one position in the list; clicking the down arrow icon moves a grouping rule down one position in the list.
