Help about dashboard chart drilldown

Dear Sir,

I would like to create hierarchy inside spago BI tool to make drill down in it, after going through the Tutorial provided by your team I have found that there is option
called "$P{ ParKpiHierarchy}".

Do i need to add this option to spagobi.xml configuration file ??
And If I'm right so far, how to write this tag into the xml config. file ??

Hi,

I am also facing same issue? did you get the error resolved?

Thanks in advance
Nisha.
