A Section Report may have multiple nested groups. Each group contains a Header Section and a Footer Section. A Header Section prints before any Detail Section in a group. A Footer Section prints after all Detail Sections in a group. Sections of a group are inserted immediately before and after a Detail Section. The number of times a Section of a group can print depends on how data is grouped. A Section Report starts a new group (Header, Detail, and Footer) for each change on data gathered in that group.
