I have a simple SSRS report connecting to an SSAS cube that displays all the sales by employee for a day. The report displays correctly and shows me all employees and its sales, in descending order.
But the users don't want to see all the sales; they just want to see the top N. So I added a Top N operator filter to the dataset, and the value of that filter (ie. the N) comes from parameter @TopN (Expression: [Sales], Operator: Top N, Value: [@TopN]).
So the current available static values for @TopN are 20, 50, 100, and that works correctly; I select "20" in the parameter dropdown and the top 20 sellers are displayed.
To those parameter options, I want to add "Show All", and if they choose that option, then all the employees will be shown. With this option, a user can display the top 20, 50, or 100 sellers, or just display all the sellers.
How would I be able to do that?
Thanks.
I ended up using Eric Hauenstein's solution.
