Group header and footer sections are automatically inserted when you define a group. They are inserted at a level between the report header and footer, and the detail section.
Typically, you would use the group header to print a group title and the group footer to print the group totals or some other summary.
For an example of group headers and footers, see the example shown in "Detail Section", earlier in this section. In this example, the grouping is based on customer name. The customer name is the group header and the total for each group is in the group footer.
For full details about creating groups, see "Creating Groups", later in this chapter.
