Report Groups allow you to run multiple reports at one time.
Report Groups allow you to save time by creating report "packages" consisting of multiple reports. All reports are automatically concatenated into one file by default, creating a "combined report".
When you want to save time.
Report Groups are set up in the Report Explorer interface:
Here you can add/edit/delete Report Groups.
The Add Reporting Group form allows you to enter a Name and Description for the Group, as well as select which reports you want to add to the Group.
When you check a Report in the list, it automatically is added to the Selected Reports section. Use the Left/Right arrow keys to add/remove additional reports to the Group. Use the Up/Down arrows to put the Reports in the order you want them:
To run a Report Group from the Project Explorer or the Project Editor, you will find them listed under the Other button on the Ribbon:
There is a Report Setting that you can turn off if you want each Report in the Report Group to run as separate files, i.e. - do not concatenate.
