A Developer’s Guide to the ABAP RESTful Programming Model

An Introduction to Developing Cloud Applications Using the RAP Model

To help ABAP developers meet the business needs of their organizations and make coding more efficient, SAP provides programming models. These models have changed over the years as requirements and technologies have changed, and now, with the user experience taking center stage in a constantly evolving business landscape, a flexible and efficient development model that optimally supports SAP Fiori, SAP HANA, and sophisticated technologies has become a pressing need. To meet this need, SAP now offers the ABAP RESTful programming (RAP) model.
