The ABAP RESTful application programming model (RAP) is the cornerstone of modern development for SAP—get on the cutting edge with this guide! Develop applications from the ground up, from data modeling with CDS to interface generation with SAP Fiori elements. Walk through concrete use cases, including managed and unmanaged scenarios, and then adapt your applications to the SAP BTP, ABAP environment. You’re on your way to working with RAP!


In this book, you’ll learn about:

a. 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.

b. 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.

c. 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.

Highlights include:
1) Application development
2) Managed and unmanaged scenarios
3) Core data services (CDS)
4) Behavior definition
5) Entity manipulation language (EML)
