Top 10 (not using dimension limits)

[#1]

I want to show the percentage of sales for the top 10 products against the total sales. How can I do this?

At the moment I am using dimension limits on the following expression sum(sales) to give me the sum of sales for the top 10 products

But how do I then write this in the form of an expression without using dimension limits?

Many thanks.
