WorkFlow BADI : Get Responsi From R/3 for given WBS

Question

Hi,
Scenario:
I am developing a Workflow BADI in SRM5.0.
For all cost centers I am getting approvers based on Z-table values.
But then for WBS... i have to get the list of approvers from R/3.
I created a Function module in R/3 dev which gets me Responsible person.
Issue:
While calling the RFC function module... by giving destination name, the Function module is working fine.
But I dont want to Hardcode Destination name.
Can I get the Destination name in some other manner ?
Helpful Answers will be rewarded.
Regards,
Ashwin.

Hi,
Please follow this logic:
1) Function Module BBP_GET_BACKEND_SYSTEMS  will provide you the backend system detail (logical system name).
2) Then use the FM BBP_LOGICAL_SYSTEM_GETDETAIL to get the RFC destination of the backend system which can be used to make teh RFC call.
This would avoid hard coding and will work fine.
Sample Code:
*& Report  ZKB_BACKEND_SYS
REPORT  zkb_backend_sys.
DATA: lt_log_sys     TYPE TABLE OF bbps_logical_system.
DATA: lt_messages    TYPE TABLE OF balmi.
DATA: ls_log_sys     TYPE bbps_logical_system.
DATA: lv_destination TYPE rfcdest.
CALL FUNCTION 'BBP_GET_BACKEND_SYSTEMS'
  TABLES
    et_logical_systems = lt_log_sys
    et_messages        = lt_messages.
CLEAR ls_log_sys.
READ TABLE lt_log_sys INTO ls_log_sys INDEX 1.
CHECK sy-subrc EQ 0.
CALL FUNCTION 'BBP_LOGICAL_SYSTEM_GETDETAIL'
  EXPORTING
    logical_system = ls_log_sys-logsys
  IMPORTING
    destination    = lv_destination
  EXCEPTIONS
    not_found      = 1
    OTHERS         = 2.
IF sy-subrc <> 0.
  MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
          WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
ENDIF.
WRITE:/ 'RFC Destination is:', lv_destination.
