Federated Portal- BI iview showing error

Hi,

I am implementing Federated Portal Network.

I have created a Proxy-to-Portlet IView (WSRP) . URL iviews are fetched as normal. But when I preview BI iviews , I get the following message:

codecom.sap.portal.appintegrator.sap.BWReport::GlobalPortal/ReturnToConsumer

MandatoryParameters

sap-pp-consumerBaseURL

OptionalParameters[/code]

any idea what the mandatory parameter sap-pp-consumerBaseURL is?

Or is there any other method by which we should create federated portal content for BI iviews on producer consumer.
