SAP Portal 7.31 - Fiori integration

Dear All,

We are planning to configure Portal –Fiori. Portal is totally with BI reports. Should we need to do any SSO for Fiori ??

Current Portal level is 7.31 SP20.

There are many docs in detailed on only particular area  but I didn't see any step by step docs for initial starters!!.

Can anyone share steps what need to setup/check for scratch please.

below I can see few details but not clear for start level

Thanks
