Master-detail report

There is a possibility for a master-detail report?
I have a master table and, for each row in this table, 0 or more lines of 3 
different detail tables.

I need a structure like:

- "Master" record header

   - "detail 1" record header
   - 0 or more "detail 1" detail report
   - "detail 1" record footer

   - "detail 2" record header
   - 0 or more "detail 2" detail report
   - "detail 2" record footer

   - "detail 3" record header
   - 0 or more "detail 3" detail report
   - "detail 3" record footer

- "Master" record footer
- Report footer

How can I get info/examples for this layout?

Regards

Franco Spinelli
