How do I create subtotals in a report?

[Guest]

I'm trying to add subtotals to a report based on each product.

This question would be better asked in the Reports NG.

However, view the Sorting and Grouping dialog and set a level to your
Product field. Display the group footer (or header) and add text boxes to
the section like:
=Sum([YourNumericField])
