Non-Cumulative keyfigure example

Question

Hi all,
      To test for non-cumulative keyfigures I have modeled a keyfigure noofemployees and below is my model
<b>Infocube has following characteristics, timecharacteristics and keyfigures</b>
Charteristics: Companycode
TimeChar: 0calmonth
Keyfigures: salesrevenue and noofemployees
<b>My infosource has following infoobjects</b>
Companycode,0calday,salesrevenue,nofoemployees
In update rules, I wrote a formulae(0calmonth2) to convert 0calday to 0calmonth.
I want to generate a report to know for every company, its monthly sales and number of employees.
I created numberofemployees as a cumulative keyfigure with exception aggregation as Maximum(to get the maximum number of employees in one month instead of aggregating the values).  I don't know if I am doing something wrong, but my keyfigure noofemployees is aggregated for each month. 
Please let me know if I created the keyfigure noofemployees correctly.
thanks,
Sabrina.

Hi Sabrina,
A non-cumulative keyfigure can be modeled in BW either using
-a cumulative keyfigure that stores the non-cumulative value changes of the non-cumulative keyfigure or
-Two cumulative keyfigures which represent the inflow and outflow values of the non-cumulative keyfigure.
The keyfigures used to define the non-cumulative keyfigure - keyfigure for non-cumulative value change or keyfigures for inflow and outflow - should themselves be cumulative keyfigures and have the following properties.
•     Standard aggregation -> Summation
•     Exception aggregation -> Summation
So as per the definition you first create a cumulative Key figure to capture the non-cumulative value changes of the non-cumulative keyfigure.Say ZKF1 and assign following properties:
Aggregation: Summation
Exception Aggregation:Summation.
Now create a Non-cummulative Key Figure say ZKF2 and assign following properties:
Aggregation: Summation
Exception Aggregation:Last Value
Non Cummulative Value Change:ZKF1.
This will give you non-cumulative keyfigures "number of employees" correctly.
Hope this helps.Please grant points if it solves your purpose.
