Entering Header Information for a Report Group 
Use
A report group contains reports from one
library that use similar data and present this data in different ways. The header information of a report group contains information that is valid for the report group as a whole (such as setting or suppressing the indicator for the regeneration of the report group and the configuration of the report/report interface).
If you define reports for the report/report interface in both the report group header and in the report group’s library, the system uses the reports that you have defined specifically for the report group.
Prerequisites
You have reached step 3 of the procedure
Creating a Report Group. On the Create Report Group screen you have already chosen Goto ® Header and are on the screen Create Report Group: Header.Procedure

If you select this indicator, when you call the report group only a warning message will appear telling you that this is not an up-to-date generated report group. Until the report group is regenerated, you can only call it with the definitions valid at the time of the last generation.

Report groups are regenerated automatically after importing Support Packages, after an upgrade or after a release upgrade, even if you have set the Not automatic indicator. The system also automatically regenerates report groups if the programs generated, or the stored definitions and sets, have been deleted.
You can define reports for the report/report interface in both the report group header and in the report group’s library. The reports you enter in the library are valid for all reports that use the same library. If you define reports for the report/report interface in both the report group header and in the report group’s library, the system uses the reports that you have defined specifically for the report group.
The reports you enter as the receiver reports can be Report Writer reports, Report Painter reports, ABAP programs, report portfolio reports, drilldown reports, or transactions.
