marianol Posted April 16, 2014 Share Posted April 16, 2014 A subdataset cannot pass parameters to the main report flow.If you need to do that you will need to use SUBREPORTS instead of Datasets.Here is a good tutorial on using subreports in general: http://community.jaspersoft.com/wiki/subreports-jaspersoft-studio#Creation_of_the_Second_Subreport and this one http://community.jaspersoft.com/wiki/subreportsIn this guide http://community.jaspersoft.com/documentation/ireport-ultimate-guide on Chapter 17.3 (page 324) it explains in detail how passing values from the subreport to the main report: Link to comment Share on other sites More sharing options...
