For most standard reports of the system, developers reports have implemented the ability to set fields by which data in the report will be grouped.
Predefined groupings are available to the user in the Quick Settings panel:
In the default "Group by" section user may select attributes that would be used for group data in the report and the user may set the order of groups (move them using the up and down arrows 
).
Grouping of data in the report by selected fields will be applied in the order in which they are located in the Group by section.
...
To adjust grouping settings, open the Grouping Fields tab. Depending on the report's structure level (upper area), you can add or change groupings.
