- RAP Objects

RAP objects are special CDS objects that support ABAP RAP:

• Service definitions for RAP business services (BS)

• Behavior definitions for RAP business objects (BO)

RAP business services provide access to CDS entities by Web clients from outside an AS ABAP. Such an access can be a pure read access (query) or a transactional request.

• For read accesses (queries), all accesses from the AS ABAP to the underlying database are encapsulated by the RAP transactional engine. Normally, no own ABAP programming is necessary. Only in exceptional cases, special CDS custom entities can be used, that are implemented in ABAP classes.

• For transactional requests, RAP business objects (RAP BOs) are required. In a RAP BO, a behavior is defined by a CDS behavior definition for a CDS entity, that can be exposed by a RAP business service. The behavior is implemented by the managed RAP BO provider or in ABAP behavior implementations.

More information about ABAP RAP can be found under ABAP RESTful Programming Model.
