Hi Amit
You can find a lot of content on SCN on calculation views to CDS views for S/4 HANA. I'm not a pro in that area but searching for a few minutes gives me plenty of interesting results, check this blog post out where a community member discusses about a migration path for calculation views to CDS views and discusses around the "why" this change happens:
https://blogs.sap.com/2016/09/26/core-data-services-cds-in-sap-s4-hana/
On the IBP, that's part of BPC I assume which is part of 'EPM ~aka Enterprise Performance Management' from a roadmap perspective.
I cannot find much on this except for the fact that the product availability matrix (https://support.sap.com/pam) has SAP BPC 10.1 version for SAP Netweaver listed as a component relevant to S/4 HANA 1610 ~ navigating to S/4 HANA 1610 and there checking related components shows the below for example:
SAP PC 10.1 FOR SAP NW
SAP Business Planning and Consolidation 10.1, version for SAP NetWeaver
So I would except that to work.
Hope this helps but otherwise I would advise you to get in touch with SAP in a more direct manner so you get your questions answered.
Best regards
Tom
