Hi,

I would like to know how to configure Single sign-on (SSO) for my SAP BI 7.0 system(includes SAP BI Portal and BEx, IGS, Pre-calculation server) and also the requirements and prerequisites for the same..

My company started SSO implementation for other SAP syatems, SO I would liket to know how to configure and proceed for my SAP BI system.

Please any one respond on this and guide me, also it would be nice if you provide me some step by step kind of documentation on this.

Best Regards,
