The SAP ABAP RESTful Application Programming Model (RAP) is the strategic development model for building modern SAP applications on SAP S/4HANA and SAP Business Technology Platform (BTP). RAP enables developers to create scalable, secure, and SAP HANA-optimized business applications while significantly reducing development effort through model-driven development techniques.

In this detailed guide, you will explore the complete journey of developing a read-only SAP RAP application. Starting with the setup of the ABAP development environment using Eclipse ADT, you will learn how to create ABAP packages, design CDS-based data models, implement UI annotations, create service definitions, and expose business data through OData services.

Key topics covered include:

• Introduction to SAP RAP architecture and development concepts
• Understanding read-only and transactional application scenarios
• Creating and managing ABAP packages for RAP development
• Building Core Data Services (CDS) views for data modeling
• Applying UI annotations for SAP Fiori applications
• Creating service definitions and service bindings
• Exposing data as OData services using SADL
• Best practices for SAP HANA-optimized application development
• Preparing applications for SAP Fiori Elements consumption
• Understanding the transition from read-only to transactional RAP applications

This guide is ideal for SAP ABAP developers, SAP consultants, SAP BTP developers, SAP Fiori developers, and technical architects who want to gain hands-on experience with SAP’s modern application programming model.
