Multiple documents (PDFs) from ONE rptdesign-file.

[WFG]

Probably one of the easiest tasks but I can't find any documentation.

I have a dataset with tons of data for e.g. several departments.
I want to generate one seperate document for each department. Naturally, I could spend a parameter (department-id) and build each report seperately (one call to the engine for each department-id) - but: is there a way (Scripting?) to let the report generate itself multiple times, grouped by an element of the dataset???

Many thanks
