Hi, I have my main report and a sub-report.

Column headings in subreport don't show so I added a Group Header in the subreport for the labels with the RepeatSection property of the group header to Yes.

Problem - I see group header repeated after every record.

I fixed it by:

Open report in design mode
Click design tab
Click Group & sort
Select Group on “the field to group by” (in my case Date)

Then the multiple headers disappeared.

hope this helps somebody :)
