Top N based on formual result

Printed From: Crystal Reports Book — Forum Name: Technical Questions

I have a formula to add together summary formulas. Is there a way to sort the Top N of the summary formula result?

My summary formula -
Sum ({@Code-IO}, {field})+Sum ({@Code-O}, {field})+Sum ({@Code-VI}, {field})+Sum ({@Weapon}, {field})

I want to get the Top N of the result of the summary formula for a group.
