HI,

write this after PAI..

PROCESS ON VALUE-REQUEST.

FIELD ifmtp-form_type MODULE fm_drop.

PROCESS ON HELP-REQUEST.

FIELD srno MODULE help_srn.

MODULE fm_drop INPUT.

  CLEAR ifmtp.
  REFRESH ifmtp.

  ifmtp-form_type = 'C'.
  APPEND ifmtp.
  ifmtp-form_type = 'F'.
  APPEND ifmtp.
  ifmtp-form_type = 'H'.
  APPEND ifmtp.

  CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
    EXPORTING
      retfield  = 'FORM_TYPE'
      value_org = 'S'
    TABLES
      value_tab = ifmtp.
  IF sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
  ENDIF.

ENDMODULE.                 " fm_drop  INPUT

here ifmtp-form_type is my field which i have taken as listbox on screen...

DATA : BEGIN OF ifmtp OCCURS 0,

form_type LIKE zform_track_mast-form_type,

END OF ifmtp.

for this,

i have taken one text field on screen 2000

and provide info about this field...

MODULE help_srn INPUT.

CALL SCREEN 2000 STARTING AT 10 5

ENDING AT 60 10.

ENDMODULE. " help_srn INPUT

MODULE user_command_2000 INPUT.

CASE sy-ucomm.

WHEN 'OK' OR 'CAN'.

LEAVE TO SCREEN 0.

ENDCASE.

ENDMODULE. " USER_COMMAND_2000 INPUT

reward if usefull...

Program your own. let me give a code sample just for the POV section. Here the F4 help is coded for the field "GV_USER" of screen 100 and "ADDR_TO" and "ADDR_CC" fields of your work area used for the table control's internal table.

DATA: BEGIN OF gt_mail OCCURS 0 ,

...

addr_to(255) TYPE c ,

addr_cc (255) TYPE c ,

...

END OF gt_mail .

DATA gv_user like sy-uname .

...

*--Screen 100:

...

PROCESS ON VALUE-REQUEST.

FIELD gv_user MODULE f4_user .

FIELD gt_mail-addr_to MODULE f4_addr_to .

FIELD gt_mail-addr_cc MODULE f4_addr_cc .

-

---

MODULE gv_user INPUT.

*--Branching to a form since the variables are defined

*-as global when you define here...

PERFORM f4_user CHANGING gv_user .

ENDMODULE .

*--

MODULE f4_addr_to INPUT.

PERFORM f4_user CHANGING gt_mail-addr_to .

ENDMODULE .

*--

MODULE f4_addr_cc INPUT.

PERFORM f4_user CHANGING gt_mail-addr_cc .

ENDMODULE .

-

---

FORM f4_user CHANGING ep_user LIKE sy-uname .

*You can have this internal table as you want

DATA: BEGIN OF lt_users OCCURS 1 ,

bname LIKE usr21-bname ,

kostl LIKE usr21-kostl ,

END OF lt_users .

DATA lt_return LIKE ddshretval OCCURS 0 WITH HEADER LINE .

*You can get the internal table content from any table

*you want. Here I use "USR21"

SELECT bname kostl FROM usr21

INTO TABLE lt_users .

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

*retfield must contain the name of the field of the

*internal table which will be assigned to your screen

*field in case you select it.

retfield = 'BNAME'

window_title = 'User Selection'

value_org = 'S' "Use this value

TABLES

value_tab = lt_users "your int. tab holding values to be selected

return_tab = lt_return "int table having your selection(s)

EXCEPTIONS

parameter_error = 1

no_values_found = 2

OTHERS = 3.

IF sy-subrc = 0 .

READ TABLE lt_return INDEX 1 .

IF sy-subrc = 0 .

ep_user = lt_return-fieldval . "Here is the assignment

ENDIF .

ENDIF.

ENDFORM .

In fact, there is a FM "F4_USER" but it says that it is obsolete and recommends the usage of "USER_ADDR" search help object.

There is function module documentation for "F4IF_INT_TABLE_VALUE_REQUEST" .

If you apply both ways, SAP will execute the code in POV and ignore the search help object.

step by step procedure for POV is as follows:

1First write process on value-request in flow logic after process after input.

process on value-request.

field ztable-fieldname module rec_help.

2 Now double click on module rec_help for code.

3 module rec_help input.

data : begin of it_tmp occurs 2,

fieldname like ztable-fieldname

fieldname2 like ztable-fieldname2

data : end of it_tmp.

data: progname like sy-repid,

dynnum like sy-dynnr.

data : t_return like ddshretval occurs 0 with header line.

refresh it_tmp.

select * from ztable client specified

where mandt = sy-mandt

and fieldname2= ztable1-fieldname2.

move-corresponding ztable to it_tmp.

append it_tmp.

endselect.

call function 'F4IF_INT_TABLE_VALUE_REQUEST'

exporting

retfield = 'fieldname1'

dynpprog = progname

dynpnr = dynnum

dynprofield = 'fieldname1'

value_org = 'S'

tables

value_tab = it_tmp

return_tab = t_return

endif.

if sy-subrc = 0.

read table t_return index 1.

ztable-fieldname1 = t_return-fieldval.

endif.
