I want no blank pages. How should I set it up?

Solution

  • The page format on your subreport is currently set to pageHeight="802" which equals one full A4 page and that's why it's using a full page in your main report.

    I'd recommend adjusting the page format of the subreport to match the allocated space in the main report.
