This repository contains the material for the SAP TechEd 2025 session AD164 – Get started with ABAP Cloud for classic ABAP developers.
The ABAP Cloud development model (ABAP Cloud) is the development model to build business apps, services, and extensions that follow the clean core principles by default on SAP BTP, SAP S/4HANA Cloud, and SAP S/4HANA as of release 2022. It is an integral part of SAP Build.
In this workshop, you’ll get hands-on experience with ABAP Cloud and grasp how the new concepts work. Building on your knowledge of classic ABAP, you’ll learn how to develop cloud-ready business apps and services. You'll use the ABAP RESTful application programming model (RAP) which is used for building transactional scenarios. Based on a practical scenario, you will rebuild an existing ALV-based app as an a modern SAP Fiori app with RAP, and extend it further with new capabilities.
The business context for the scenario is as follows:
The department responsible for managing worldwide Travels for multiple Agencies is requesting you to build a new SAP Fiori app, Manage Travels, with different capabilities to process travel bookings. More information on the scenario and the app will be given throughout the exercises.

Note
Please note that the focus of this hands-on workshop is on backend development – specifically, developing OData UI services, including the UI semantics for the SAP Fiori elements UI – rather than on SAP Fiori UI development.
Important
For attendees of on-site SAP TechEd 2025 event:
Please note that appropriate backend systems will be provided by SAP for the hands-on worskops offered at one of the on-site SAP TechEd events in 2025 – i.e., SAP TechEd Berlin 2025, ASUG Tech Connect 2025, and SAP TechEd Bangalore 2025.
Laptops with the required ADT installation will also be provided to attendees of SAP TechEd Berlin 2025 and SAP TechEd Bangalore 2025.
Follow the steps below to build the Travel app based on an OData service on top of a draft-enabled RAP Business Object (BO) to develop a transactional Fiori elements List Report app from scratch using RAP.
Note
Instead of using existing ABAP Cloud generators to generate all basic ABAP development artifacts required for building the Manage Travels app, you'll build them step by step to better understand the ABAP Cloud development model, especially the ABAP RESTful Application Programming Model (RAP) in this workshop. The Block B below contains demo videos on the existing classic and AI-based ABAP Cloud generators.
Exercises 1-7 provided in the block are the main focus of this hands-on workshop.
The ABAP development tools for Eclipse provide various standard and AI-based ABAP Cloud generators to create all required development artifacts – from the database table and the CDS objects to the RAP BO and OData service – that you've created manually for learning purposes in this hands-on workshop. See how to use them in the demo provided.

The exercises below are optional and can be completed by participants if time permits. They extend the application scope covered in the main exercises (1–7) by adding modify authorization checks and full transactional enablement of the Travel BO — that is, create, update, and delete operations. This also includes the opportunity to explore the Entity Manipulation Language (EML).
