    SAP ABAP RESTful Programming Model (RAP) represents SAP’s modern approach to building business applications, embracing RESTful principles while maintaining ABAP’s robust business capabilities. At its foundation, RAP transforms the Application Server ABAP into a stateless web server, perfectly aligned with modern web architecture principles.

    ABAP RAP leverages OData as its RESTful protocol, enabling seamless communication between web clients and the SAP system. Rather than maintaining state in the application server, session data is stored in the standard database, adhering to true RESTful principles. The architecture is built around Core Data Services (CDS) entities and specialized RAP objects, providing a clean separation of concerns.
