F4 Help on Date Field after ALV is generated

Question

Hi all,
Now this might sound very simple question, but Im having some difficulty in this.
My idea is to have an F4 on a date field after the ALV Grid report is executed. From the forum search, Ive got such answers as
l_fieldcat-edit         = 'X'.
l_fieldcat-F4AVAILABL = 'X'.
Now the problem with this is that Im getting an error saying:
The data object "l_fieldcat does not have a component called "F4AVAILABL".
And then I tried this:
l_fieldcat-fieldname    = 'DDATE'.
l_fieldcat-ref_tabname = 'ZCST001'.
Now at the report output when I press F4 on the date field it gives me a dump saying:
Field symbol has not yet been assigned.
Error in the ABAP Application Program
The current ABAP program "CL_GUI_ALV_GRID===============CP" had to be terminated because it has come across a statement that unfortunately cannot be executed.
So Im kinda stuck now. Appreciate your suggestions.
PS: Im on ECC6.
PPS:The intended F4 on field is a custom field in a custom table.

Run This:
report ztest.
TYPE-POOLS : slis.
tables:mara,makt.
data: begin of it_final occurs 0,
matnr like mara-matnr,
ERSDA like mara-ERSDA,
end of it_final.
DATA: it_fieldcat     TYPE slis_t_fieldcat_alv,
      wa_fieldcat     TYPE slis_fieldcat_alv,
      wa_layout       TYPE slis_layout_alv,
      g_repid         TYPE sy-repid.
START-OF-SELECTION.
select matnr ERSDA into table it_final from mara up to 10 rows.
  g_repid = sy-repid.
  PERFORM f_populate_fieldcat.
*  PERFORM fill_zpayroll.
  PERFORM f_call_alv.
*&      Form  f_populate_fieldcat
*       text
*  -->  p1        text
*  <--  p2        text
form f_populate_fieldcat .
"Mat Number
  CLEAR wa_fieldcat.
  wa_fieldcat-tabname     = it_final.
  wa_fieldcat-fieldname   = 'MATNR'.
  wa_fieldcat-seltext_l   = 'MAT No.'.
  wa_fieldcat-outputlen   = 15.
  APPEND wa_fieldcat TO it_fieldcat.
  "Creation date
  CLEAR wa_fieldcat.
  wa_fieldcat-tabname     = it_final.
  wa_fieldcat-fieldname   = 'ERSDA'.
  wa_fieldcat-edit         = 'X'.
wa_fieldcat-REF_TABname = 'MARA'.
wa_fieldcat-REF_FIELDname = 'ERSDA'.
  wa_fieldcat-seltext_l   = 'Creation date '.
  wa_fieldcat-outputlen   = 15.
  APPEND wa_fieldcat TO it_fieldcat.
endform.                    " f_populate_fieldcat
*&      Form  f_call_alv
*       text
*  -->  p1        text
*  <--  p2        text
form f_call_alv .
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
    EXPORTING
      i_callback_program     = g_repid
      i_callback_top_of_page = 'TOP-OF-PAGE'
      is_layout              = wa_layout
      it_fieldcat            = it_fieldcat[]
      I_SAVE = 'A'
    TABLES
      t_outtab               = it_final
    EXCEPTIONS
      program_error          = 1
      OTHERS                 = 2.
  IF sy-subrc <> 0.
    EXIT.
  ENDIF.
endform.                    " f_call_alv
In custom table date field must be referenced to DATS.
P.S.I hope you already solved
