First Steps in SAP ABAP RESTful Application Programming Model (RAP)
詳細
From legacy to innovation! This book provides ABAP developers and SAP consultants with a practical introduction to the latest evolutionary stage of ABAP programming for SAP—the ABAP RESTful Application Programming Model (RAP). RAP enables the development of cloud-capable and future-proof applications in SAP S/4HANA.
Delve into the fundamentals and key components of RAP, including Business Objects (BO), their behavior definition and business services. Learn about Entity Manipulation Language (EML)—a new addition to ABAP—and examine methodologies such as numbering, determinations, validations, actions, functions, drafts, and hierarchies in the RAP model. Explore the details of custom entities, which enable data to be obtained from various sources, including OData web services and non-SAP systems.
This book provides a combination of theory and practical examples to demonstrate the potential applications of RAP, and explains how to use it to create powerful, reliable software that will add value to your company.
- Fundamentals of RAP—introduction to business objects, and their behavior and services
