Hi all,

Field length is 4 and is of 'char' type. The values are getting displayed in the f4 help, but the problem is , I'm not able to select any of the values. Please suggest a solution.

Thanks.

Hello Pranil,

Maybe you did not give the READ statement

Try this..


PARAMETERS:
 p_carr TYPE s_carr_id,
 p_conn TYPE dfies-fieldname.
DATA:
  w_repid LIKE sy-repid,
  w_dnum LIKE sy-dynnr,
  t_return LIKE TABLE OF ddshretval WITH HEADER LINE.
DATA:
  BEGIN OF tab OCCURS 0,
    carrid LIKE spfli-carrid,
    connid LIKE spfli-connid,
  END OF tab.

AT SELECTION-SCREEN.
  IF p_carr IS NOT INITIAL.
    SELECT carrid connid
      FROM spfli
      INTO TABLE tab
     WHERE carrid EQ p_carr.
  ELSE.
    SELECT carrid connid
      FROM spfli
      INTO TABLE tab.
  ENDIF.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_conn.

Hii!

After calling function module for F4 help, you have to assign

'fieldval' of structure ddshretval to your screen field(parameter).

Here after calling function module . i have used

p_carrid = table1-fieldval.

Check this sample code


REPORT  z_test11 .


PARAMETERS:
  p_carrid(2).



DATA: table1 LIKE
             ddshretval
    OCCURS 0 WITH HEADER LINE.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_carrid.


CALL FUNCTION 'F4IF_FIELD_VALUE_REQUEST'
  EXPORTING
    tabname                   = 'scarr'
    fieldname                 = 'carrid'
*   SEARCHHELP                = ' '
*   SHLPPARAM                 = ' '
*   DYNPPROG                  = ' '
*   DYNPNR                    = ' '
*   DYNPROFIELD               = 'p_carrid'
*   STEPL                     = 0
*   VALUE                     = ' '
*   MULTIPLE_CHOICE           = ' '
*   DISPLAY                   =  ' '
*   SUPPRESS_RECORDLIST       = ' '
*   CALLBACK_PROGRAM          = ' '
*   CALLBACK_FORM             = ' '
*   SELECTION_SCREEN          = ' '
 TABLES
   RETURN_TAB                 = table1
 EXCEPTIONS
   FIELD_NOT_FOUND           = 1
   NO_HELP_FOR_FIELD         = 2
   INCONSISTENT_HELP         = 3
   NO_VALUES_FOUND           = 4
   OTHERS                    = 5
          .
IF sy-subrc <> 0.
 MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
 p_carrid = table1-fieldval.

write: p_carrid.

Hi,

If it is ALV then check whether the field is in editable mode or not.

Hi Pranil,

Try this...

DATA : t_dynmap LIKE dselc OCCURS 0 WITH HEADER LINE,

t_fldtab LIKE dfies OCCURS 0 WITH HEADER LINE.

DATA : return TYPE TABLE OF ddshretval WITH HEADER LINE.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR s_pz-low.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

retfield = 'FIELD'

dynpprog = 'ZTEST'

dynpnr = '1000'

dynprofield = 'S_PZ-LOW'

value_org = 'S'

window_title = 'TEST VALUES'

TABLES

field_tab = t_fldtab

value_tab = it_pz

return_tab = return

dynpfld_mapping = t_dynmap.

Read return table and place that on low value of S_PZ

READ TABLE return INDEX 1.

s_pz-low = return-fieldval.

where it_pz is an internal table in which I hv the values.

Mamtha
