In this article I would like to show you how much more you can do with the regular functions of Business Objects.

First of all I would like to start with function **SUM**

If you ever want to get the global sum of a table and work on table value sum like getting a relative average of a summed value over global sum.

Let's assume you have a cross table

.... CATEGORY1 CATEGORY2 SUM Average

Male 10 20 30 42.85%

Female 15 25 40 57.15%

SUM 25 45 70

Average 35.71% 64.28%

So in order to get the averages you need to divide the sum to global sum:

So your average formula will be:

**=Sum([Sales]) / (Sum([Sales]) In Report)**

Yes In Report provide global sum

If you ever work on cumulative sum of values, you need to be careful about how your cumulative results go

**=RunningSum([Sales];Col;([Company]))**

Here second option provide you to go with **Col** or **Row** in terms of your cumulative direction.

The third option is your break point. Like your cumulative results will be reset on each company so you will have cumulative sum in each respective Company, otherwise it will keep summing the result in global scale.

Get the table and see the results by playing around with the formula.
