ABAP CDS - ABAP Annotations

The following tables summarize all ABAP annotations in the CDS DDL and CDS DCL in ABAP CDS. ABAP annotations are SAP annotations that are evaluated by the ABAP runtime environment. The precise semantics of these annotations are described under the relevant scope section in the documentation.

• AbapCatalog-Annotations

• AccessControl-Annotations

• ClientDependent-Annotations

• ClientHandling-Annotations

• DataAging-Annotations

• EndUserText-Annotations

• Environment-Annotations

• MappingRole-Annotations

• Metadata-Annotations

• Semantics-Annotations

Note

An ABAP annotation can also be evaluated by frameworks of other software components.
