RAP (RESTful ABAP Programming Model)

Guide for building transactional applications using the ABAP RESTful Application Programming Model (RAP) in ABAP Cloud.

Workflow

1. Determine the user's goal:

   • Creating a new RAP BO from scratch
   • Adding behavior (actions, validations, determinations) to an existing BO
   • Writing EML statements to consume a RAP BO
   • Troubleshooting RAP-related issues
   • Understanding RAP concepts

2. Identify the scenario:

   • Managed (greenfield) vs. unmanaged (brownfield)
   • Draft-enabled or not
   • Numbering concept: early/late, internal/external/managed
   • Single entity or composition tree (root + children)
