Hi Saleha,
                In order to add F4 help to a field in modeule pool follow these steps:-
1. First go to SE11 and create your own search help( if you dont know how to create a search help please feel free to ask me, it is very easy).
2. Now in your module pool program program go to the layout of your screen.
3. Now when you see the attributes of this field in the Dict tab you will find the field Search Help. Now here you can specify the name of the search help you created in SE11.
There is also another mehtod to create the dynamic search help. eg:- in a posted document data get the Document nos related to that company code.
The sample code is like this:-
First of all declare the module below in the flow logic of your screen then create it in your main program.
You declare the module in the PROCESS ON VALUE-REQUEST.
PROCESS ON VALUE-REQUEST.
FIELD TXT_DOCNO MODULE VALUE_BELNR.
You also need to create an internal table where you wil store results of the select query fired below in the module.
here you will get a F4 help on the filed Document Number(TXT_DOCNO) based on the field Company code (TXT_CODCO)
MODULE VALUE_BELNR INPUT.
progname = sy-repid.
  dynnum   = sy-dynnr.
  CLEAR: field_value, dynpro_values.
  field_value-fieldname = 'TXT_CODCO'.
  APPEND field_value TO dynpro_values.
CALL FUNCTION 'F4IF_FIELD_VALUE_REQUEST'
    EXPORTING
      tabname     = 'BKPF'
      fieldname   = 'BUKRS'
      dynpprog    = progname
      dynpnr      = dynnum
      dynprofield = 'TXT_CODCO'.
CALL FUNCTION 'DYNP_VALUES_READ'
       EXPORTING
            dyname             = progname
            dynumb             = dynnum
            translate_to_upper = 'X'
       TABLES
            dynpfields         = dynpro_values.
  READ TABLE dynpro_values INDEX 1 INTO field_value.
  SELECT  BUKRS BELNR
    FROM  BKPF
    INTO  CORRESPONDING FIELDS OF TABLE it_doc1
    WHERE BUKRS = field_value-fieldvalue.
CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
       EXPORTING
            retfield    = 'BELNR'
            dynpprog    = progname
            dynpnr      = dynnum
            dynprofield = 'TXT_BELNR'
            value_org   = 'S'
       TABLES
            value_tab   = it_doc1.
ENDMODULE.                 " VALUE_BELNR  INPUT
Hope you find this information useful, let me know.
