ABAPHANDLER_METH_AUTH - HANDLER METH AUTH

Fill RESBD Structure from EBP Component Structure PERFORM Short Reference
This documentation is copyright by SAP AG.

FOR INSTANCE AUTHORIZATION, AUTHORIZATION

Handler method definition:

METHODS meth $[FINAL$]
   FOR $[INSTANCE$] AUTHORIZATION
   $[IMPORTING$] ${ REFERENCE(im_par_auth) $| im_par_auth $}
   REQUEST ${ REFERENCE(req_auth) $| req_auth $}
   FOR bdef
   RESULT ${ REFERENCE(res_auth) $| res_auth $}
  $[CHANGING ${ $[ failed TYPE data$] $[reported TYPE data$] $}$].

Effect

Handler method that is used for instance-based authorization checks for accessing RAP BO entities. It must be defined and implemented in a handler class of an ABAP behavior pool. The method name meth can be chosen freely. bdef is the name or the alias of the BDEF.

Method Parameters

IMPORTING parameters:

im_par_auth: Internal table of type TYPE TABLE FOR AUTHORIZATION KEY.

The parameter can also be passed by reference (see REFERENCE). The use of the ABAP word IMPORTING is optional.

req_auth: Request parameter on which the information retrieval for instance-based authorization is based on. It is a structure of type TYPE STRUCTURE FOR AUTHORIZATION REQUEST. The parameter can also be passed by reference.

CHANGING parameters:

res_auth: Used to store the result of the permission information retrieval. It is an internal table of type TYPE TABLE FOR AUTHORIZATION RESULT. The parameter can also be passed by reference

The CHANGING parameters failed and reported are implicitly available. They are used to return information on failures or messages respectively. It is possible to specify the parameters with the predefined names failed and reported explicitly following the ABAP word CHANGING. In this case, the generic type DATA is used. At runtime, the typed parameters implicitly have the BDEF derived type TYPE RESPONSE FOR.

BDEF Requirements

See the required BDEF notations for both variants in the topic CDS BDL - authorizations.

Examples

Examples for RAP handler method definitions. Find demonstrations of method implementations in the executable examples further down.

METHODS get_instance_authorizations FOR INSTANCE AUTHORIZATION
    IMPORTING keys REQUEST requested_authorizations FOR bdef
    RESULT result.

METHODS get_instance_authorizations FOR AUTHORIZATION
    IMPORTING keys REQUEST requested_authorizations FOR bdef RESULT result
    CHANGING failed TYPE DATA reported TYPE DATA.

Example for RAP Handler Methods: Demonstrates this RAP handler method within a RAP handler class using a simple unmanaged RAP BO that is draft-enabled.
