Interface BDEF, New Field Characteristics
In RAP interface behavior definitions, the following RAP field characteristics are now available:
Interface BDEF, use event
In RAP interface behavior definitions,
RAP business events
can be reused using the syntax use event.
Managed and Unmanaged RAP BO, New Field Characteristic
A new RAP field characteristic
is available for managed and unmanaged RAP BOs: notrigger[:warn]. Fields with this attribute must not be used in a trigger condition of a
RAP validation or a
RAP determination.
Static Default Factory Actions
The syntax addition default is available for static factory actions in managed, unmanaged, and projection BDEFs. Exactly one static factory action per
RAP BO entity can be
defined as default static factory action. The addition default is evaluated by consuming frameworks, such as OData.
RAP Derived Events
RAP derived events allow the reuse of existing
RAP business events with a custom payload. RAP derived events are available in managed and unmanaged RAP BOs and in
base BDEF extensions.
They are defined using the syntax managed event.
RAP Side Effects
RAP side effects define
interdependencies among RAP BO properties that trigger a reload of the affected properties on the user
interface. Side effects are translated into annotations in the OData metadata of a RAP service. The
syntax for defining RAP side effects is side effects.
Draft Action Activate Optimized
The optional addition optimized
is now available for the draft action Activate.
SAP recommends always using this addition, since it speeds up the activation of draft instances.
Authorization Control on Action Level
Two new RAP BO operation additions are available for actions and determine actions:
Both of these additions are specified on the action level and they replace the authorization control that is specified in the authorization master entity.
In managed, unmanaged, and projection BDEFs, these additions are optional. In
base BDEF extensions, authorization control on the action level is mandatory.
with managed instance filter
The optional addition with managed instance filter is available for
projection BDEFs and
interface BDEFs. If specified, the WHERE condition of the underlying
CDS transactional query or
CDS transactional interface is evaluated when the BDEF is accessed with
ABAP EML or OData requests from Web clients.
Abstract BDEF Extensions
The new statement extension for abstract of the RAP BDL makes it possible to add
abstract BDEF extensions to
abstract behavior definitions.
Abstract BDEFs are mainly used as parameters for RAP actions, RAP functions, and RAP business events. An abstract BDEF extension allows you to extend these parameters.
Abstract BDEF, mandatory:execute for Associations
The optional addition mandatory:execute is now available for associations in
abstract BDEFs. It declares the association in question as mandatory, that is, whenever the abstract BDEF is used as an
input parameter for a
RAP action or a
RAP function, the
%control flag must be set for this association.
Redefined Parameters, Projection or Interface BDEF
The input or output parameter of a RAP action,
RAP function, or a
RAP business event that is
reused in a
projection BDEF or an
interface BDEF can optionally be replaced with a dedicated projection-specific
structure using the syntax additions deep
parameter or deep result.
Draft Action AdditionalSave
A new draft action is available,
draft action AdditionalSave. This draft action allows users to define
a custom saving strategy for draft instances. It is intended in particular for draft actions with a user-defined implementation, defined using the addition with additional implementation.
BOPF-Based RAP Business Objects
A migration tool has been released to migrate CDS-based BOPF business objects to BOPF-based RAP business objects. For details on BOPF-based RAP business objects, see the topic RAP - BOPF-Based RAP Business Objects.
