ABAP RESTful Programming Model or ABAP Programming Model

[former_member640435]

Hi,

I'm an abap developer, working on S/4HANA 1809 (on premise).
I will have to do some FIORI development.

I read some documents, blogs, posts, about the RESTful Programming Model.
Apparently this model is only available since S/4HANA 1909 (on premise).
Then I have to use the ABAP Programming Model in my project, right ?

I will Buy a book about this subject in SAP Press, but I have a doubt in 2 books :
- ABAP RESTful Programming Model
- ABAP Programming Model for SAP Fiori

In my situation I think the best is "ABAP Programming Model for SAP Fiori".
But if someone can confirm that ?
I guess the RESTful Programming with Service Binding and Service Definition and ... are not available for me.

Regards,
Youri

You are right it's available from 1909 on Prem, but even in 1909, it doesn't have a lot of features and if you want to work on a proper transactional based CDs view which needs the draft support, it won't be coming to restful.programming model any time soon..

So for now the best choice is to go with abap programming model for fiori.

About the book, I saw somewhere restful programming model book has abap programming model content included as well, you probably have to confirm by yourself on that..

For me the best source of Truth is sap help, it has very detailed (very very 😄 ) examples about abap programming model for fiori even for RAP.. just give it a try if you haven't yet.

Newer version of help about that model is also available for new sps.

Thanks,
