You can use Miscellaneous/Create OpenDocument from Template to create reports.
You need to create an OpenOffice file (in any of the openoffice file formats) which will server as the template on which the report is based. The openoffice template can include Freemarker markup for additional flexibility, and control of your report.
In addition, you can use the Convert to PDF and Convert Document templates, to output the resulting openoffice document to PDF and office formats.
A demo of these features is available as part of the Examples sample project (see the Document Generation perspective) which is installed with the installation kit, and is also available for testing and download from here.
