What does it do? BDEF derived type used for RAP response parameters and operands of ABAP_EML statements for the purpose of providing or storing RAP responses. The BDEF derived types with TYPE RESPONSE FOR ... are basically deep structures containing one internal table as nested component for each entity of the RAP BO. Therefore, all information on all entities of a RAP BO can be provided and retrieved at once. bdef stands for the source name of a RAP BO root entity. The addition EARLY applies to responses from within the RAP interaction phase; the addition LATE applies to responses in the RAP save sequence. Where Used
The three predefined formal parameters of RAP handler methods and RAP saver methods mapped, failed and reported - whose names are also reflected in the syntax here - are typed with these BDEF derived types. In ABAP behavior pools, the parameters of the said methods typed with this BDEF derived type are implicitly available. The following images show the F2 help information in ADT for a RAP handler method for which the response parameters have not been explicitly specified: METHODS create FOR MODIFY IMPORTING entities FOR CREATE demo_unmanaged_root_2. F2 help information in ADT: IMAGE type_response_for2.png 705 134 The parameters can also be explicitly specified. When specified explicitly, for example, for a RAP handler method that creates instances and that includes ... FOR MODIFY ... FOR CREATE ..., the syntax can be as follows. Note that for the explicit declaration of the changing parameters, the generic type DATA is used. At runtime, the typed parameters implicitly have the type TYPE RESPONSE FOR .... METHODS create FOR MODIFY IMPORTING entities FOR CREATE bdef CHANGING failed TYPE DATA mapped TYPE DATA reported TYPE DATA.
The operands following the MAPPED , FAILED and REPORTED additions of nondynamic forms of ABAP_EML statements are typed with these BDEF derived types. ABAP_NOTE The operands following these additions in dynamic ABAP_EML statements are internal tables of type ABP_BEHV_RESPONSE_TAB, see here. The operands store the RAP responses when an ABAP_EML statement triggers the calling of a method in the behavior pool. One example is the internally created data object f_resp in the statement MODIFY ENTITY ... FROM ... FAILED FINAL(f_resp) ....
In ABAP programs, these BDEF derived types can also be used to declare data objects and types, for example, as follows: DATA f TYPE RESPONSE FOR FAILED demo_managed_root.
TYPES r TYPE RESPONSE FOR REPORTED demo_managed_root.
DATA m TYPE RESPONSE FOR MAPPED demo_managed_root. Details on the Syntax
