Hi Sri

Use the FM F4IF_INT_TABLE_VALUE_REQUEST in the event AT SELECTION-SCREEN ON VALUE-REQUEST FOR <sel parameter>.


  CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
    EXPORTING
     retfield               = 'KUNNR'
     dynpprog               = sy-repid
     dynpnr                 = sy-dynnr
     dynprofield            = S_KUNNR'
     value_org              = 'S'
    TABLES
      value_tab             = li_f4_kunnr
    EXCEPTIONS
      parameter_error       = 1
      no_values_found       = 2
      others                = 3.
  IF sy-subrc NE 0.
  ENDIF.

Fill li_f4_kunnr with the values for kunnr.

Thanks

Hi Sri,

Suppose your field name is : wa_lic_scs-lic_typ

After PAI you need to write a code like this. This will surely help you.

PROCESS ON VALUE-REQUEST.

This provides the F4 help for the field - License Type

FIELD wa_lic_scs-lic_typ MODULE f4_help_scs.

Now Module f4_help_scs.

Hii,

Check out these different ways...for creating Input Helps.

Input help can be programmed in selection screen using event

AT SELECTION-SCREEN ON VALUE-REQUEST FOR FIELD and for module pools in event

PROCESS ON VALUE_REQUEST using module call starting with FIELD

i.e FIELD field MODULE module

There ar number of function modules that can be used for the purpose, but these

can fullfill the task easily or combination of them.

DYNP_VALUE_READ

F4IF_FIELD_VALUE_REQUEST

F4IF_INT_TABLE_VALUE_REQUEST

POPUP_WITH_TABLE_DISPLAY

DYNP_VALUE_READ

This function module is used to read values in the screen fields. Use of this

FM causes forced transfer of data from screen fields to ABAP fields.

There are 3 exporting parameters

DYNAME = program name = SY-CPROG

DYNUMB = Screen number = SY-DYNNR

TRANSLATE_TO_UPPER = 'X'

and one importing TABLE parameter

DYNPFIELDS = Table of TYPE DYNPREAD

The DYNPFIELDS parameter is used to pass internal table of type DYNPREAD

to this FM and the values read from the screen will be stored in this table.This

table consists of two fields:

FIELDNAME : Used to pass the name of screen field for which the value is to

be read.

FIELDVALUE : Used to read the value of the field in the screen.

e.g.

DATA: SCREEN_VALUES TYPE TABLE OF DYNPREAD ,

SCREEN_VALUE LIKE LINE OF SCREEN_VALUES.

SCREEN_VALUE-FIELDNAME = 'KUNNR' . * Field to be read

APPEND SCREEN_VALUE TO SCREEN_VALUES. * Fill the table

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

DYNAME = SY-CPROG

DYNUMB = SY-DYNNR

TRANSLATE_TO_UPPER = 'X'

TABLES

DYNPFIELDS = SCREEN_VALUES.

READ TABLE SCREEN_VALUES INDEX 1 INTO SCREEN_VALUE.Now the screen value for field KUNNR is in the SCREEN_VALUE-FIELDVALUE and can be used for further processing like using it to fill the internal table to be used as parameter in F4IF_INT_TABLE_VALUE_REQUEST ETC.

F4IF_FIELD_VALUE_REQUEST

This FM is used to display value help or input from ABAP dictionary.We have to pass the name of the structure or table(TABNAME) along with the field name(FIELDNAME) . The selection can be returned to the specified screen field if three

parameters DYNPNR,DYNPPROG,DYNPROFIELD are also specified or to a table if RETRN_TAB is specified.

CALL FUNCTION 'F4IF_FIELD_VALUE_REQUEST'

EXPORTING

TABNAME = table/structure

FIELDNAME = 'field name'

DYNPPROG = SY-CPROG

DYNPNR = SY-DYNR

DYNPROFIELD = 'screen field'

IMPORTING

RETURN_TAB = table of type DYNPREAD

F4IF_INT_TABLE_VALUE_REQUEST

This FM is used to dsiplay values stored in an internal table as input

help.This FM is used to program our own custom help if no such input help

exists in ABAP dictionary for a particular field. The parameter VALUE_TAB is used to pass the internal table containing input values.The parameter RETFIELD

is used to specify the internal table field whose value will be returned to the screen field or RETURN_TAB.

If DYNPNR,DYNPPROG and DYNPROFIELD are specified than the user selection is passed to the screen field specified in the DYNPROFIELD. If RETURN_TAB is specified the selectionis returned in a table.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

RETFIELD = field from int table whose value will be returned

DYNPPROG = SY-CPROG

DYNPNR = SY-DYNNR

DYNPROFIELD = 'screen field'

VALUE_ORG = 'S'

TABLES

VALUE_TAB = internal table whose values will be shown.

RETURN_TAB = internal table of type DDSHRETVAL

EXCEPTIONS

parameter_error = 1

no_values_found = 2

others = 3.

POPUP_WITH_TABLE_DISPLAY

This FM is used to display the contents of an internal table in a popup window.The user can select a row and the index of that is returned in the CHOISE

parameter.The VALUETAB is used to pass the internal table.

A suitable title can be set using TITLETEXT parameter. The starting and end position of the popup can be specified by the parameters STARTPOS_COL / ROW and ENDPOS_ROW / COL .

CALL FUNCTION 'POPUP_WITH_TABLE_DISPLAY'

EXPORTING

ENDPOS_COL =

ENDPOS_ROW =

STARTPOS_COL =

STARTPOS_ROW =

TITLETEXT = 'title text'

IMPORTING

CHOISE =

TABLES

VALUETAB =

EXCEPTIONS

BREAK_OFF = 1

OTHERS = 2.

e.g.

DATA: w_choice TYPE SY-TABIX.

DATA: BEGIN OF i_values OCCURS 0 WITH HEADER LINE,

values TYPE I,

END OF i_values.

PARAMETRS : id TYPE I.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR id

i_values-values = '0001'.

APPEND i_values.

i_values-values = '0002'.

APPEND i_values.

i_values-values = '0003'.

APPEND i_values.

i_values-values = '0004'.

APPEND i_values.

CALL FUNCTION 'POPUP_WITH_TABLE_DISPLAY'

EXPORTING

ENDPOS_COL = 40

ENDPOS_ROW = 12

STARTPOS_COL = 20

STARTPOS_ROW = 5

TITLETEXT = 'Select an ID'

IMPORTING

CHOISE = w_choice

TABLES

VALUETAB = i_values

EXCEPTIONS

BREAK_OFF = 1

OTHERS = 2.

CHECK w_choice > 0.

READ TABLE i_values INDEX w_choice.

...now we can process the selection as it is contained

...in the structure i_values.

Hope this is Helpful,

Regards,

Sandy.
