I have a report with a subreport for detail. The report has a couple customers who end up having what looks like identical subreports showing up in the detail when I run the report. I have found one case where the subreport is returning slightly different data. I only have one subreport in the parent report so I don't know why this would happen. If I look at the query that is the basis of the subreport, I can't find duplicated data that would cause the problem. It doesn't seem to make sense to me.
