How to create a workflow dealing with customizing program(Add-on program)

Question

Dear ALL,
I am new to workflow and I was assigned to create a workflow related to an customizing program(Dynpro screen).
I know we can refer to some std. template for workflow developing.
However, I don't know how to create a brand new workflow to deal with the add-on program and table.
My major difficulty is how to create a new object:
--How to create the new event to track the operation of add-on program, for example, push 'submit' button.
--How to create method to update the add-on table.
I do hope someone could give me some guidance.
Thank,
Gary

This is a Function Module that triggers an event ob Business Object tht you will create by making a subtype of Business Object. Use Transaction Code SWO1 to do so.
FUNCTION zwf_process_trip.
""Local Interface:
*"  IMPORTING
*"     VALUE(I_EMP_NUMBER) TYPE  PERNR_D
*"     VALUE(I_EMP_TRIP) TYPE  REINR
  INCLUDE <cntn01> .
  DATA:i_emp_details TYPE STANDARD TABLE OF p0001,  "Employee Details
       wa_request    TYPE p0001,                    "Workarea for Employee details
       v_country_grp TYPE molga,                    "Country SubGrouping
       v_object_key  TYPE sweinstcou-objkey.        "Key for the buisness object ZWOBUSTRIP
  CONSTANTS: c_bo_trip     TYPE swo_objtyp VALUE 'ZWOBUSTRIP',
             c_event_trip  TYPE swo_event  VALUE 'TripCreate',
             c_infy_type_1 TYPE infty      VALUE '0001'.
Event Container declaration
  swc_container i_event_cont.
  swc_create_container i_event_cont.
Reading the INFO TYPE 0001 to obtain the
Employee details
  CALL FUNCTION 'HR_READ_INFOTYPE'
    EXPORTING
      pernr           = i_emp_number
      infty           = c_infy_type_1
      begda           = sy-datum
      endda           = sy-datum
    TABLES
      infty_tab       = i_emp_details
    EXCEPTIONS
      infty_not_found = 1
      OTHERS          = 2.
SY-SUBRC check is not required as the error
handelling will be done by WorkFlow rule
resolution.
  CLEAR wa_request.
  READ TABLE i_emp_details INTO wa_request INDEX 1.
  IF sy-subrc = 0.
  Retrieving the Country SubGrouping for the employee
    SELECT SINGLE molga
      FROM t001p
      INTO v_country_grp
     WHERE werks = wa_request-werks
       AND btrtl = wa_request-persk.
  ENDIF.
Sending the relevant data to event container
  swc_set_element i_event_cont 'EmpId'     i_emp_number.
  IF sy-subrc <> 0.
No Processing needed.
  ENDIF.
  swc_set_element i_event_cont 'PersonnelArea'    wa_request-werks.
  IF sy-subrc <> 0.
No Processing needed.
  ENDIF.
  swc_set_element i_event_cont 'CountryGrouping' v_country_grp.
  IF sy-subrc <> 0.
No Processing needed.
  ENDIF.
  swc_set_element i_event_cont 'EmpSubGrp'       wa_request-persk.
  IF sy-subrc <> 0.
No Processing needed.
  ENDIF.
  swc_set_element i_event_cont 'EmpTripId'       i_emp_trip.
  IF sy-subrc <> 0.
No Processing needed.
  ENDIF.
Raising the event to trigger the workflow
  v_object_key = i_emp_number.
  CALL FUNCTION 'SWE_EVENT_CREATE'
    EXPORTING
      objtype           = c_bo_trip
      objkey            = v_object_key
      event             = c_event_trip
    TABLES
      event_container   = i_event_cont
    EXCEPTIONS
      objtype_not_found = 1
      OTHERS            = 2.
  IF sy-subrc <> 0.
No Processing needed.
  ENDIF.
  COMMIT WORK.
ENDFUNCTION.
SWEL Transaction Code is used to track event linkage.
SWUS is used to test Workflow manually with single test.
