Hi, Rafael. Users (such as report developers), if they have the proper permissions, can create input controls in the Ad Hoc editor. You can find information on using the Ad Hoc Editor to define input controls in the JasperReports Server User Guide, beginning with section 4.7, Using Filters and Input Controls. You can download or view the User Guide from the Docs tab, above, or by clicking the link below: http://community.jaspersoft.com/documentation?version=7114 If this doesn't give you enough information, leave me a comment and I'll see if I can find a better answer for you. aimee
