Provides a structured, end-to-end guide to building RAP-based transactional ABAP Cloud applications, including data modeling, behavior definitions, ABAP behavior pools, EML, draft handling, and business events.
Create a simple RAP managed BO scenario and define a basic behavior with one action to illustrate the workflow.

To build a transactional ABAP Cloud app with RAP, you define data models, behavior definitions (BDEF), behavior implementation pools, and expose services. This covers data modeling, behavior implementation patterns, validations, and service exposure for complete application workflows.
Managed RAP behavior pools rely on the framework for standard CRUD operations, while unmanaged pools require custom logic for all operations. Both approaches support draft-enabled scenarios, with managed being faster for greenfield implementations and unmanaged for brownfield integrations.
EML (Entity Manipulation Language) statements in ABAP execute CRUD operations and actions on RAP business objects. You use EML to trigger create, update, delete, and custom action operations within behavior pools, enabling transactional data processing and draft handling.
Yes, RAP business objects support draft handling and side effects. You can enable draft scenarios in the behavior definition to preserve incomplete data, configure side effects to trigger dynamic UI updates, and manage validations during draft persistence.
Validations and error handling in a RAP behavior definition are implemented within ABAP behavior pools. You define validation rules in the BDEF and implement the logic in the behavior pool, returning structured error messages to ensure data integrity during EML operations.
RAP development supports both greenfield and brownfield scenarios in ABAP Cloud. For brownfield implementations, unmanaged behavior pools allow you to wrap existing legacy ABAP logic and expose it through modern RAP service definitions.
