Hi JRK
Thank you for response.
Earlier I missed to include some info
We are in 3.1 Live and installed 4.0 in separate server .
3.1 reports published in netweaver portal, after that in the same portal have published BI 4.0 reports too.
for achieving this , at BI 4.0 server end we changed port number.
when open 4.0 webi reports it is asking for user credentials, it shouldn't be.
we want to configure SSO with Netweaver Portal.
Thanks in advance.
