Hi Veena
These two keyfigures are calculated keyfigures (CKF), just as the naming convention says. In your query designer, just below your infoprovider name in the top left, you will find Calculated Keyfigures and Restricted Keyfigures as below.
You will find you keyfigure as well in this list.Right click on it and click on display. It will show you the explanation.
It should be based on a keyfigure from your infocube or another CKF or RKF.
Hope this helps
Regards
