ABAP & Development

What is ABAP RESTful Application Programming Model (RAP)?

SAP's model for building transactional and analytical Fiori apps and APIs using CDS, behavior definitions, and services.

RAP defines business objects with behaviors such as create, update, actions, and validations, exposed via OData V2 or V4. It is the standard model for ABAP Cloud. RAP business objects can be tested with ABAP Unit and API tests.
