When working with Tivoli Common Reporting v1.3 you may want to create a report that will only show the top number ‘n’ of the data. A common error is using topCount() which will return the top ten results but if two results contain the same value it will add both of them. For example a set of numbers such as (1,2,3,4,5,6,7,8,9,10,11,1) would actually show a graph of eleven items because of the repeated ‘1’. This is a step-by-step guide on how to create a report which will truly limit the results to a given number N.
