To add header information to a group, create an additional header for the report. Refer to Additional Headers and Footers for more information about creating additional headers. The additional header contains the field or fields that each group is based on, and will be printed once for each group on the report. It also typically contains descriptive column headers for the information that appears in each group.
For example, the following illustration shows the layout for the User Classes report. Notice that user information is grouped according to the User Class, and then Account Access, and so on. An additional header is used for each group category for the report.
