Hi,
Analytics available with S/4HANA is called SAP S/4HANA Embedded Analytics. This is part and parcel of SAP S/4HANA system and does not require separate licenses or any separate deployment units or components to be installed. S/4HANA Embedded Analytics comes with its own tools and standard content for ex: Analytical Fiori apps, Smart Business apps, Query browser app, Query designer app etc. The foundation of all thest tools and apps are CDS views which are the core entities in S/4HANA system.
BI platform, on the other hand, is platform for strategic analytics which is more classified as source agnostic and there are variety of tools available with this platform. Many of these tools are compatible with S/4HANA CDS views (via the INA protocol) for ex: Design Studio, Analysis Office etc. However, BI platform requires additional licenses.
The standard content with these BI platform tools based on S/4HANA CDS views is available and part of SAP Best Practices for SAP S/4HANA: http://service.sap.com/s4op
This standard content can also be downloaded from the above link and then 'Find out more' section -> More about this solution -> Download technical content for Analytics
There are plans to evolve this standard BI content across varioius key Business Processes as part of SAP Best Practices for SAP S/4HANA.
Hope this helps.
Best Regards,
Somesh
