Crystal Reports - Show group headings on drill down reports only

sometimes, when you want to drill down your drill down report will contain a number of records and you only want to show the headings once and only show them on the drill down report.

To achieve this, put a second section into the group header (right click on the header and choose 'insert section below)

Move the headings into the new section and then choose Section Expert

click the X-2 logo button and enter the following formula

if drilldowngrouplevel =0 then true

The group headers will then only show on the drill-down report.
