Use the Group Sorting screen to sort groups you created on the Grouping Screen. You can sort all groups, or you can choose the top or bottom 5 groups. When sorting by the top or bottom 5 groups, you can also choose the summarized field you want to base the sorting on.
This screen appears only if you've specified a group on the Grouping Screen and a summary on the Summaries Screen. Creating a group sort is an optional step in the wizard.
If you choose Top 5 or Bottom 5, your report displays data for only those groups; no other groups appear on your report.
