Bdc upload file data into internal table problem with gui_upload fm

Question

Hello experts,
my coding is like this ..
data : begin of itab occurs 0 .
field1 like mara-matnr,
field2......
etc,
end of itab.
data: file1 type string.
parameter :file like rlgrap-filename.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR file.
CALL FUNCTION 'KD_GET_FILENAME_ON_F4'
EXPORTING
static = 'X'
mask = space
field_name = 'FILE'
CHANGING
file_name = file.
START-OF-SELECTION.
FILE1 = FILE . "HERE I AM PASSING INTO STRING
CALL FUNCTION 'GUI_UPLOAD'
EXPORTING
filename = FILE1
FILETYPE = 'ASC'
has_field_separator = 'X'
TABLES
data_tab = itab. " here the data is not populating from the file , it is giving the error like speified table not found.
HERE i am getting the message like "specified table name not recgonised" . the data is not populating into the itab from the file.
file structure is same as the internal table.
I stored the file as .txt( ie in notepad).
my file is like this..
10000 200 323 sunndarrr.......
i had a problem with this bdc , i am getting like "specified table name not recgonised" in the fm gui_upload while debugging.
when i am using the ws_upload it is working fine.
please guide me where i have done the mistake.
thank you so much for all the replies.

Hi,
Have a look on the following code.
TABLES: kna1.
DATA: BEGIN OF itab1 OCCURS 0,
      str(255),
      END OF itab1.
DATA: itab2 TYPE kna1 OCCURS 0 WITH HEADER LINE.
CALL FUNCTION 'WS_UPLOAD'
  EXPORTING
    filename                = 'D:\ABAP EVE\ffile1.txt'
    filetype                = 'ASC'
  TABLES
    data_tab                = itab1
  EXCEPTIONS
    conversion_error        = 1
    file_open_error         = 2
    file_read_error         = 3
    invalid_type            = 4
    no_batch                = 5
    unknown_error           = 6
    invalid_table_width     = 7
    gui_refuse_filetransfer = 8
    customer_error          = 9
    no_authority            = 10
    OTHERS                  = 11.
IF sy-subrc <> 0.
  WRITE:/ 'sorry'.
ELSE.
  LOOP AT itab1.
    SPLIT itab1-str AT ',' INTO itab2-kunnr itab2-name1.
    APPEND itab2.
  ENDLOOP.
  IF sy-subrc = 0.
    LOOP AT itab2.
      WRITE:/ itab2-kunnr,itab2-name1.
      INSERT INTO kna1 VALUES itab2.
    ENDLOOP.
    IF sy-subrc = 0.
      WRITE:/ 'inserted'.
    ELSE.
      WRITE:/ 'not inserted'.
    ENDIF.
  ELSE.
    WRITE:/ 'fail'.
  ENDIF.
ENDIF.
Flat file:
10001,Sadney
10003,Yogesh
20005,Madan
1.U need to define internal table with one field of max size
2.upload the flat file data into that internal table
3.split that internal table data into another internal table(having fields)
