Value hep problem in web dynpro application

Question

Hi All,
I have a requirement where I need to add a field for alternate payee to the web dynpro application and the field name is BSEG-EMPFB. I have written the following code to get the values of it based on the vendor number:
SELECT SINGLE * FROM  lfb1 INTO f4lfb1_z
                  WHERE lifnr = lv_lifnr
                  AND   bukrs = '001'."bseg-bukrs'.
  CALL FUNCTION 'FI_VENDOR_ALTERN_PAYERS_READ'
    EXPORTING
      i_lifnr            = lv_lifnr
      i_filkd            = filkd
      i_bukrs            = '001'
      i_lfb1_head_office = f4lfb1_z
    TABLES
      t_zemtab           = t_zemtab.
  LOOP AT t_zemtab INTO w_zemtab.
    ls_value_set-text = w_zemtab-empfb.
    ls_value_set-value = w_zemtab-empfb.
append ls_value_set to lt_value_set.
DATA lo_nd_alt_payee_info TYPE REF TO if_wd_context_node_info.
DATA lo_nd_alt_payee TYPE REF TO if_wd_context_node.
lo_nd_alt_payee = wd_context->get_child_node( name = wd_this->wdctx_alt_payee ).
lo_nd_alt_payee_info = lo_nd_alt_payee->get_node_info( ).
         lo_nd_alt_payee_info->set_attribute_value_set(
            name =  `ALTERNATE_PAYEE`
            value_set = lt_value_set )
Now the problem is user wants the details of the alternate payee as F4 help and when I debugged the standard FV60 functionality this how the F4 help is being build therE:
REFRESH fldtab.
  CLEAR fldtab.
  fldtab-tabname    = 'IZEMTAB'.
  fldtab-fieldname  = 'EMPFB'.
  fldtab-selectflag = 'X'.
  APPEND fldtab.
  CLEAR fldtab.
  fldtab-tabname    = 'IZEMTAB'.
  fldtab-fieldname  = 'NAME1'.
  APPEND fldtab.
  CLEAR fldtab.
  fldtab-tabname    = 'IZEMTAB'.
  fldtab-fieldname  = 'ORT01'.
  APPEND fldtab.
  CLEAR fldtab.
  fldtab-tabname    = 'IZEMTAB'.
  fldtab-fieldname  = 'STRAS'.
  APPEND fldtab.
*------- Fill Values for Function Module Call --------------------------
  REFRESH valtab.
  LOOP AT zemtab.
    valtab-feld = zemtab-empfb.
    APPEND valtab.
    valtab-feld = zemtab-name1.
    APPEND valtab.
    valtab-feld = zemtab-ort01.
    APPEND valtab.
    IF zemtab-stras NE space.
      valtab-feld = zemtab-stras.
    ELSEIF zemtab-pfach NE space.
      CONCATENATE 'Postfach:'(019) zemtab-pfach INTO valtab-feld.
    ELSE.
      valtab-feld = space.
    ENDIF.
    APPEND valtab.
  ENDLOOP.
*------- F4 Dialog -----------------------------------------------------
  CALL FUNCTION 'HELP_VALUES_GET_WITH_TABLE'
    EXPORTING
      display      = space
      fieldname    = 'EMPFB'
      tabname      = 'INVFO'
    IMPORTING
      select_value = empfb
    TABLES
      fields       = fldtab
      valuetab     = valtab.
  IF NOT empfb IS INITIAL.
    invfo-empfb = empfb.
  ENDIF.
can you please tell me how can I accomdate this in the web dynpro application?
Thnaks,

Hi Raja,
Search help is availble at dictinary level you get F4 help automatically.
Otherwise create OVS help for alternate payee. use WDR_OVS.
