Yes. Before you run the report load the records field into the app
context like:
task.getAppContext().put("myrecords", records);
The report can then be written to use a scripted data source
http://www.eclipse.org/birt/phoenix/examples/scripting/scripteddatasource/
to read the values. In the scripted data set open method your can get
access to the records like:
myrecords = reportContext.getAppContext().get("myrecords");
You should then be able to use the fetch method to iterate over myrecords.
