Probably the fact is that I do not know the product enough.
But it would be really useful to implement a "drill down" feature in the product.
Often the user wants to know an aggregate value (ie, the sum of sales in the quarter) and then wants to know the details (the individual sales that give that value).
Hence, the aggregate value should be an hyperlink to a detail page.
Probably it is possible to create a master - detail relationship using views, but what it is really needed is to click on the number and have the detail page that pops up.
