Purpose

A wiki for myself and everybody who is interested in developing ABAP using CDS (and/or HANA CDS).

A redesign of the content will follow the next few weeks. Time is limited, that's why I cannot name a date.

Overview

Most of the content will answer questions which I had to fight in the beginning using CDS. So this might be a good place to start with, because I also start using the CDS feature at the moment(smile)

Here is how Björn Goercke introduce CDS

New Core Data Services Features in SAP HANA 1.0 SPS 10 - Update on CDS by Thomas Jung

CDS - One Concept, Two Flavors - Difference between HANA-CDS and ABAP CDS by Horst Keller

Getting Started

Getting Started with ABAP Core Data Services - this is a great set of links by Carine Tchoutouo Djomo (It includes some of the links provided here, but also many others). It seems to be frequently updated.

 End to End Guide HANA to Fiori <-- Jasmin also added a very good part of CDS, it is worth to read it

Annotations (in NW 7.5)

http://scn.sap.com/community/abap/blog/2015/11/13/abap-news-for-release-750--annotations-in-abap-cds - really useful introduction, with useful links, by Horst Keller.

 

CDS Annotations for Metadata-Driven UIs - PDF (ca 60 pages) by Jasmin Gruschke with lots of information on the UI annotations


What comes next

In the next weeks I will take some time to build different CDS and want to compare the CDS on different databases and of course SAP HANA

So stay tuned and contact me if you miss something here.

  1. Hi Florian,

    1. Hi Julie,

      thank you for the addition here. Good to see that there are more people like me out there(smile)

  2. Hi Florian,

    First of all thank you for your effort.

    Since you say "developing ABAP using CDS" but link to Thomas Jung's blog about news in HANA CDS, I'm afraid there's some confusion about these concepts, Therefore,  I wrote a small blog http://scn.sap.com/community/abap/blog/2015/07/20/cds--one-model-two-flavors, hoping to clarify a bit.

    Best

    Horst

     

    PS: B.T.W., curly brackets are availlable in real ABAP (not only ABAP CDS) since 7.02 ... 

     


     

    1. Hi Horst,

      thank you for adding a comment here. Your absolutely right. I also recognized the difference during the ABAP on HANA Codejam with Jasmin. At the moment I'm thinking about splitting it in two categories to not confuse someone (and of course me(smile))

  3. Hi 

    Khushdeep Singh

    ,

    For some reason, I have been notified of your comment, but I can't see it (!).

    Anyway, I suggest you post your question in the SAP Community:

    https://www.sap.com/community/topic/abap.html - You will more likely get a response. 

    Best wishes,

    Julie Plummer, SAP PM.
