Effect

Extends an existing RAP type mapping with extension fields. The syntax is similar to the syntax for RAP type mapping RAP BOs, see topic CDS BDL - Type Mapping. As a prerequisite, the respective type mapping must be explicitly defined as extensible as described in topic CDS BDL - Extensibility Enabling for Managed and Unmanaged BDEFs.

Example

The BDEF extension DEMO_EXTENSION_RAP_BO extends the CDS behavior definition DEMO_RAP_FIELD_EXT. Three extension fields are added to the existing data model and the BDEF extension extends the type mapping by adding these three extension fields.

The executable example Field extension explains the example above in detail.
