Hi Rob,
Thanks for the reply. Here is the code     
Here i am passking lv_flname, lt_binary_file and updating lt_objbin
in the function module i am going to update lt_objbin.
The reason i am doing this becuase if i use open dataset it failing authorization.
Thats why i want execute these statements in background. These report will be executed by many users, so they can not give authorization for everyone.
CALL FUNCTION 'ZFI_VIM_OPEN_DATASET' IN BACKGROUND TASK
        EXPORTING
          lt_flname      = lv_flname
        TABLES
          ls_binary_file = lt_binary_file
          ls_objbin      = lt_objbin
        EXCEPTIONS
          error_dataset  = 1
          OTHERS         = 2.
Here is the function module code
FUNCTION zfi_vim_open_dataset.
*"*"Local Interface:
*"  IMPORTING
*"     VALUE(LT_FLNAME) TYPE  CHAR80
*"  TABLES
*"      LS_BINARY_FILE STRUCTURE  TBL1024
*"      LS_OBJBIN STRUCTURE  SOLISTI1
*"  EXCEPTIONS
*"      ERROR_DATASET
  OPEN DATASET lt_flname FOR OUTPUT IN BINARY MODE.
  IF sy-subrc = 0.
    LOOP AT ls_binary_file.
      TRANSFER ls_binary_file TO lt_flname.
    ENDLOOP.
    CLOSE DATASET lt_flname.
  ENDIF.
  CLEAR: ls_objbin. REFRESH: ls_objbin.
  OPEN DATASET lt_flname FOR INPUT IN BINARY MODE.
  DO.
    READ DATASET lt_flname INTO ls_objbin.
    IF sy-subrc <> 0.
      CLOSE DATASET lt_flname.
      EXIT.
    ELSE.
      APPEND ls_objbin.
    ENDIF.
  ENDDO.
  DELETE DATASET lt_flname.
ENDFUNCTION.
