Hi Devi,
Can you please check the following wiki and ensure that you are creating the iview correctly:
http://wiki.scn.sap.com/wiki/display/BOBJ/Create+URL+iview+into+the+SAP+EP+portal
What happens when you preview the iview directly in the PCD? Is the BI content displayed?
What version is the portal on?
If you still are having problems, please attach a screenshot of the iview properties in full and also a httpwatch trace
Thanks and regards,
Lorraine
