You can change the sort order of an existing report, and generate a new report based on the changed sort order, provided the report supports multiple sort orders. This new report uses the same criteria and format as the existing report.
From the Recent Reports node, right-click the report for which you want to change the sort order.
Select Change Sort Order.
In the New Report dialog, from the Sort by list, select a different sort order for the report.
The other fields in the dialog are unavailable, because you can't modify the report criteria and formats of a generated report.
Select OK.
The report is generated and is displayed in the Report View.
