ABAP_RAP - repeatable
ABAP_SYNTAX ... repeatable ...
What does it do? Defines a non-factory RAP action or a RAP function as repeatable RAP BO operation. A repeatable RAP BO operation can be executed multiple times on the same RAP BO entity instance within the same ABAP EML or OData request. The BDEF derived type of a repeatable RAP BO operation contains a %cid component and the RAP response parameters are filled for each execution individually. Regarding actions, only non-factory, instance-bound RAP actions can be declared as repeatable. Other kinds of RAP actions must not be declared as repeatable for the following reasons:
RAP factory actions are always repeatable and an explicit declaration is not necessary. The BDEF derived type of a RAP factory action contains the %cid component and multiple executions are possible.
Static RAP actions are always repeatable and an explicit declaration is not necessary. Static RAP actions are identified by means of a %cid component and multiple executions are possible.
Draft actions must not be executed multiple times on the same RAP draft instance within one request. This is not useful and not supported. The same rules apply and the same RAP BDL operation additions are available as for non-factory actions, see topic TITLE . There is only one exception: the syntax addition static is not available for repeatable actions. Regarding functions, only instance-bound functions can be declared as repeatable. Static RAP functions are always repeatable and they are identified by means of a %cid component. Therefore, an explicit declaration of the repeatable characteristic is not required and not supported. The same rules apply and the same RAP BDL operation additions are available as for functions, see topic TITLE . There is only one exception: the syntax addition static is not available for repeatable functions.

ABAP_EXAMPLE_VX5 The following example shows a managed BDEF with multiple actions and functions. ABAP_NOTE This example is intentionally kept short and simple and focuses on specific RAP aspects. It does not fully meet the requirements of the RAP BO contract. BDEF DEMO_RAP_REPEATABLE_ACTION The BDEF derived type of the non-factory instance-bound action Action does not have a %cid component. It looks as follows: IMAGE derived_type_action.jpg 424 48 The BDEF derived type of the repeatable action RepeatAction has a %cid component. It looks as follows: IMAGE repeat_action.jpg 461 65 The non-factory instance-bound action Action must not be executed multiple times on the same RAP BO entity instance. The following execution results in a runtime error. ABEXA 01743 The repeatable action RepeatAction can be executed multiple times on the same RAP BO entity instance as follows: ABAP_NOTE RepeatAction is not implemented in this example.
