Creating OData V4 Services

Requirements
You should already have a basic understanding of ABAP programming

Description
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 servicesCourse 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.
