To set A4 size at minimum page height as I have disabled pagination. So I need to maintain a fixed height even if data isn't enough to fill the full page. However, if I adjust the band height, then every time I see that gap in the report. We got the workaround from the support to use the existing main report as a subreport but Unfortunately, we cannot use subreports as our application has been designed to work with a single jrxml template only. So please take this requirement as the enhancement to allow this feature in the single jrxml template.
