Attaching notificaiton to workorder header data in IW32 txn.

Question

Hello,
I am trying to create a header notificaiton for maintenance workorder (PM09). I am able to successfully create a header notification using BAPI_ALM_NOTIF_CREATE. I am also saving the notification and updating the workorder with the header notification using BAPI_ALM_ORDER_MAINTAIN.
The notification is successfully created->saved->shows up in the object list of workorder and visible using IW33 txn. However the Notifctn field on HeaderData tab is still empty (shows a create icon besides the empty field). I am able to create this notification directly via IW32 txn by clicking on the create icon besides the Notifctn field.
Below is the code i am using
data: lv_header     type BAPI_ALM_ORDER_HEADERS_I,
      lv_method     TYPE BAPI_ALM_ORDER_METHOD,
      lv_header_up  TYPE BAPI_ALM_ORDER_HEADERS_UP.
data: l_ret type string.
MOVE-CORRESPONDING WO_HEADER to lv_header.   " work order header saved in WO_HEADER
lv_header-NOTIF_NO = wd_this->header_notif_no.
APPEND lv_header to it_header.
lv_header_up-orderid = WORK_ORDER_NUMBER.      " work order number saved before.
lv_header_up-notif_no = abap_true.
APPEND lv_header_up to it_header_up.
*----- Update method table .
lv_method-refnumber = 1.
lv_method-objecttype = 'HEADER'.
lv_method-method = 'CHANGE'.
lv_method-objectkey = WORK_ORDER_NUMBER.
APPEND lv_method to it_method.
*----- Populate other parameters for BAPI_ALM_ORDER_MAINTAIN -----*
CLEAR l_method.
  l_method-method = 'SAVE'.
  APPEND l_method TO it_method.
  CALL FUNCTION 'BAPI_ALM_ORDER_MAINTAIN'
    TABLES
      it_methods              =it_method
   IT_HEADER               = it_header
   IT_HEADER_UP            = it_header_up
    it_operation            =  it_operation
    it_operation_up         =  it_operation_up
    it_objectlist           =  it_objectlist
    it_objectlist_up        =  it_objectlist_up
      it_text                 = it_text
      it_text_lines           = it_text_line
      return                  = it_ret.
  READ TABLE it_ret INTO l_ret WITH KEY type = 'E'.
  IF sy-subrc = 0.
    e_error = l_ret.
    CALL FUNCTION 'BAPI_TRANSACTION_ROLLBACK'.
    LOOP AT lt_ret INTO l_ret WHERE type = 'E'.
     issue_error_message( l_ret ).
    ENDLOOP.
  ELSE.
The BAPI ('BAPI_ALM_ORDER_MAINTAIN') works fine for all other tasks. I am also considering implementing note 1475809, however wanted to check with others in the community for some tips.
Thanks,
Vivek

Nailed it! 
Unfortunately SAP forgets to take care of complete functionality once in a while, but luckily they put enhancement points at the right locations.
To link notification to workorder header implicit enhancement has to be implemented in FM: IBAPI_PROC_METHOD_TABLE_EXEC.
From this enhancment call FM:
CALL FUNCTION 'IOPEXT_MAKE_HEADERNOTIF'
  EXPORTING
    i_qmnum       = <fs_order_tab>-QMNUM
pass the notificaiton number in export parameter.
