Like (Open) SQL, ABAP CDS supports the following: -

1. A WHERE clause in a view definition
2. INNER joins, LEFT OUTER and RIGHT OUTER joins
3. The calculation of aggregations, grouping records, and filtering groups.

 

Each active ABAP CDS view has a corresponding ABAP Dictionary view and database views. These corresponding objects are managed automatically by the ABAP system when activating the DDL source.

 

You can use the ABAP Dictionary name, respectively the SQL view name of the CDS view in the SELECT statement FROM clause. When using the new Open SQL syntax, you can, and are recommended to, use the CDS view name, as specified using the DEFINE VIEW keywords in the DDL source file.

 

 

Enhancing Core Data Services in ABAP

 

 

To enhance a CDS view, do the following: -

1. Create a DDL source using the ADT and use the extend view <existing CDS view> with <name of the CDS entity> syntax
2. Add annotation @AbapCatalog.sqlViewAppendName to specify the name of the append to be generated as the ABAP Dictionary representation of the enhancement.
