BEX Application not displayed in EP

Hi All,

We have configured SAP BW system in EP and Enabled SSO

SSO is working fine but the problem is that we want to display BI Query on EP

and when we go to BEX Broadcaster and trying to display Query then we are getting following error

Java system error: call FM RSRD_X_GET_INFO_PROXY to ProgId BWPRD_PORTAL_EPM on host BWPRD with SSO not authorized: Authentication failed

Notification Number RSBOLAP 018

pls help us in this regard...

thanks in advance
