You can add group bands to a report by selecting the “Create Group…” command in the Overflow menu of the Report Designer toolbar. Alternatively, you can right click on the name of the report in the Outline window and select “Create Group…”. In the dialog that appears you can specify the name of the new group and the bands representing the group (Group Header and Group Footer) will be added to the Design Area of the report. You can click on any of these bands and set properties of the group band in the Properties window.

To delete a group, select the Delete Group option in the Overflow menu of the Report Designer toolbar.
