Hi Kaushik

This is a renowned subject here. Srini's suggestion is OK. And here is an example I have posted in this forum before.

*--Screen 100:
...

PROCESS ON VALUE-REQUEST.

  FIELD gv_user MODULE f4_user .

*-------------------------------
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 .
*-------------------------------

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
*--your int. tab holding values to be selected
      value_tab = lt_users 
*--int table having your selection(s)
      return_tab = lt_return 
    EXCEPTIONS
      parameter_error = 1
      no_values_found = 2
      OTHERS = 3.

  IF sy-subrc = 0 .
    READ TABLE lt_return INDEX 1 .
    IF sy-subrc = 0 .
*--Here is the assignment
      ep_user = lt_return-fieldval . 
    ENDIF .
  ENDIF.

ENDFORM .
