Implementation of Actions

To create an action, the implementing class of the action must be implemented. This class corresponds to a common ABAP class (with the /BOBF/IF_FRW_ACTION interface implemented). If you create an action using Business Object Builder (BO Builder), the generated class already implements this interface.

The action interface consists of the following methods:

Method	Description
`PREPARE`	This method is processed before the validations of the action and the `execute` method of the action are processed. Using this optional method you can enlarge or reduce the set of keys for which the action is executed.
`EXECUTE`	This mandatory method contains the business logic of the action.
`RETRIEVE_DEFAULT_PARAM`	This optional method retrieves the default parameter if an importing parameter is defined for an action. If this is the case, It can be useful for the consumer to get a default parameter proposal.

Example

The following source code describes the INVOICE_PAID action that the consumer can use to mark invoices as being paid:

Syntax Syntax

METHOD /bobf/if_frw_action~execute.
 DATA:
  lv_ltimestamp TYPE      timestampl,
  lt_root_data TYPE       bobf_t_customer_invoice,
  ls_root_data TYPE REF TO       bobf_s_customer_invoice.

" clear exporting parameter

 EXPORTING
  iv_node = if_ci_bopf_customer_invoi_c=>sc_node-root
  it_key = it_key
 IMPORTING
  et_data = lt_root_data.
" set the attributes PAYED and PAYMENT_RECEIVED
LOOP AT lt_root_data REFERENCE INTO ls_root_data.
 " update data
 ls_root_data->payed = if_sp_pay_exec_st_cd=>co_received.
 " set payment date time stamp
 GET TIME STAMP FIELD lv_ltimestamp.
 ls_root_data->payment_received = lv_ltimestamp.
 " update data
 io_modify->update(
  EXPORTING
   iv_node = if_ci_bopf_customer_invoi_c=>sc_node-root
   iv_key = ls_root_data->key
   is_data = ls_root_data ).
 ENDLOOP
ENDMETHOD

End of the code.
