Report most selling product by quantity or by revenue

Hi,

There are any report in Dynamics CRM Online where I can query what is the most selling product by quantity or by revenue?

I need to know, which is the product of my catalog that is most selling by revenue and I need to know which is the product of my catalog that is most selling by quantity

I don't know I there are any report that can do this, or if If need to create querys using orders with products and opportunities and quotes that I've won.

Thanks.
