Develop ABAP applications for SAP S/4HANA and SAP BTP
Use key tools and technologies, including core data services and SAP Fiori
Get step-by-step guidance for modeling data, implementing behaviors, developing user interfaces, and more

The Programming Model
Master the building blocks of the model. Understand REST architecture, work with CDS view entities, implement behaviors, and more. Learn about new features such as the business object interface and extensibility.

End-to-End Application Development
Develop applications for SAP S/4HANA and SAP BTP, step by step. Start by building your data model, and then create behavior definitions, implement functions, define business services, and generate your user interface.

Practical Scenarios
Apply RAP to suit your development needs. Create an application in a custom managed scenario, and then see how to integrate standard SAP functions. If you want to reuse source code, learn to adapt legacy applications for RAP in an unmanaged scenario.
