Open Pentaho Report Designer and create a new report called 'foo.report'. Don't add data sources in the Report Designer. In this report, add a Text Field and a Image URL Field element to the Page Header band. In the Item Band band, add a SubReport element.
In the SubReport that'll be called 'bar.report', add a Label element in the Report Header band and a Text Field in the Item Band band. Save and close the SubReport.
In the main report, click on the SubReport placeholder. In the Properties window, enter a Query name such as 'barQuery'.
Step 2 - Publish the Report
In Report Designer, publish the report to the BI Server. This will take the two files ('foo.report' and 'bar.report') and combine them into a report definition file (foo.xml). Publishing will also create 'foo.xaction' and 'foo.properties'.
Step 3 - Modifying the Action Sequence
In the Eclipse Pentaho Studio, open 'foo.xaction'.
