How to develop ABAP RICEF objects in S/4HANA

Hi All,

I have been wondering how the S/4 HANA framework allows for the development of ABAP RICEF objects or if there is a alternate mechanism for building these objects with S/4 HANA. From what I learn, S/4HANA will still be based on ABAP backend programs. Can we please get some details as to how the ABAP enhancement framework will work for these programs.

I understand the SAP UI5, Fiori customisations for data retrieval and User Experience at high level but an example of each of ABAP report, conversion, interface, enhancement and form development would really help visualise how S/4 HANA ABAP customisations would look like. Please let know if there is already some article on this topic.

Also I learn that the future ABAP developments will be primarily built as ABAP on eclipse, so is there a complete replacement of ABAP workbench planned? Also any new patterns recommended to be learnt for ABAP on Eclipse programming for S/4 HANA.

Thanks,

Vikrant
