在IBM Cognos 10 Report Studio中将TOP 5和其余全部汇总为“其他”

Question

I need to display top 5 clients (based on revenue) and aggregate rest all clients to just a single row 'Others' in a list report

C1 100

C2 150

C3 200

C4 250

C5 300

Others 5000

Let me know how I can achieve this.

Thank You!

Answer 1

What version of Cognos? What RDBMS?

I developed a solution for Cognos 11.0.7 and Microsoft SQL Server 2016. My solution uses two queries: Query1 gets the data, Query2 aggregates the data the way you want.

In Query1, add a Data Item named Rank that uses the rank() function. rank([Revenue])

Query2 uses all of the columns in Query1.

In Query2, change the Client column to

case
    when [Query1].[Rank] < 6
        then [Query1].[Client]
    else 'Other'
end

Here's a code sample using the GO Sales (query) sample package. This was done in Cognos 11.0.7, but it should work in Cognos 10.xx if you change the version numbers in the first line of the report spec.
