hello cool,
I have taken the Product line,product type,Revenue in list report
go to Query explorer, select the query 1
go to insertable objects and drag the dataitem in query1.
rank ([Revenue]) and change the dataitem name Rank.
rank data item drag the Detail filter,will give the Expression
[Rank]<=5.

will show the only top 5 records ...
