ABAP CDS - DDL for Data Definitions

The CDS data definitions in ABAP CDS are made using the data definition language CDS DDL in DDL source code. The CDS DDL follows the general CDS syntax rules and comprises the following statements for the definition and enhancement of CDS entities:

• Statements for CDS views

• DEFINE VIEW

• EXTEND VIEW

• Statements for CDS table functions

• DEFINE TABLE FUNCTION

• Statements for CDS hierarchies

• DEFINE HIERARCHY

• Statements for abstract CDS entities

• DEFINE ABSTRACT ENTITY

• Language elements for various CDS entities

• Entity annotations

• Input parameters

• Typings

• Element annotations

Other versions: 7.31 | 7.40 | 7.54

Notes

• The DDL source code of data definitions has its own editor in ADT, which is documented there. This can also be used to display the actual SQL DDL statement generated from the CDS DDL source text. DDL source code can also be displayed in Repository Browser in ABAP Workbench.

• Further CDS DDL statements make it possible to define annotations and metadata extensions.
