S/4HANA - ABAP RESTful Application Programming Model (RAP)

Descripción

The SAP RESTful Application Programming (RAP) course is designed to provide learners with comprehensive knowledge and hands-on experience in building sophisticated, enterprise-ready applications using SAP’s new RESTful ABAP programming model. RAP is a modern approach to developing both transactional and analytical applications on the ABAP platform. This course will equip participants with the skills to design, develop RESTful applications, ensuring they are well-versed in building scalable and maintainable solutions in an SAP environment. Participants will learn the fundamental concepts of RAP, understand its architecture, and explore how to build end-to-end applications using this framework. By the end of the course, learners will be able to implement RAP applications in SAP S/4HANA making them capable of handling complex enterprise use cases. Prerequisites: 1. Basic knowledge of ABAP Programming: Familiarity with the ABAP syntax and development environment. 2. Basic knowledge of CDS views and OData services Course Structure: 1. Introduction to RAP and Overview of the ABAP Environment: o Overview of the ABAP RESTful programming model and its components. o Setting up the development environment using Eclipse with ABAP Development Tools (ADT). 2. Core Concepts and Building Blocks of RAP: o Exploring the RAP layers: Projection, Business Object (BO), and Consumption views. o Understanding Business Object (BO) modeling and Behavior Definitions. 3. Data Modelling and Query Processing in RAP: o Creating and managing CDS (Core Data Services) views for RAP applications. o Using CDS annotations to define metadata and relationships. 4. Implementing Business Logic in RAP: o Defining and implementing Business Logic using ABAP classes. o Implementing actions, determinations, and validations. 5. OData Service Exposure and Integration: o Generating OData services from RAP BOs. o Implementing CRUD (Create, Read, Update, Delete) operations. 6. Advanced RAP Features o Using draft-enabled applications for managing long-running transactions. By completing this course, participants will gain a deep understanding of SAP RAP, making them capable of building cutting-edge applications on SAP S/4HANA, setting them apart in the evolving landscape of SAP development.
