Hi Bhaskar,
" Bhaskar I didn't Check the date of your Post, As some one updated the Very Old Thread.
" If you still face this Use the following as this is a tested one else ignore
Make your field Display only So that user can not enter or type any thing
in POV
Process on Value-Request.
field carrid module F4_carrid.
in Program.
module F4_carrid.
DATA :  begin of JTAB occurs 0,
    carrid type spfli-carrid,
end of jtab.
  SELECT * FROM SPFLI INTO TABLE JTAB.
  CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
    EXPORTING
      RETFIELD        = 'CARRID'
      DYNPPROG        = SY-REPID
      DYNPNR          = SY-DYNNR
      DYNPROFIELD     = 'CARRID'
      VALUE_ORG       = 'S'
      DISPLAY         = 'F'  " This Forces F4 Help for Display Field
    TABLES
      VALUE_TAB       = JTAB
    EXCEPTIONS
      PARAMETER_ERROR = 1
      NO_VALUES_FOUND = 2
      OTHERS          = 3.
endmodule
This is Second Option but I recommend the above method only
Or Declare Variable in TOP Include
data : f4_taken.
in PAI.
field your_field_name module Check on Input.
in POV
process on Value-Request.
field Your_field module F4_for_field
in program
module check input.
if F4_taken is initial.
message 'You have to Take F4 help only to enter a Value here' type 'E'.
else.
clear F4_taken.
endif.
endmodule
module f4_for_field.
f4_taken = 'X'.
endmodule
