I'm developing an application in Java
where I extract reports in PDF and EXCEL, using Jasper with Ireport (3.7.2) . One of these reports requires data grouped by a certain element. I gave a researched and only found resolutions with versions of old ireport that no longer are used. Can anyone tell me some way to extract the reports with their proper groupings?
Below the print of my query screen, where I should extract the data with that grouping presented. My question is if it is possible to do this in ireport and how? or an idea of how to do it.
