How to detect TAB SPACES?

Question

Hi Experts,
I'm reading an external file that contains TAB Spaces via GUI_UPLOAD, I transferred it into an internal table and tried to replace the TAB spaces with my line of code below, but still it doesn't work. Below is my line of code and also the structure of the external file that I'm reading, how can I detect TABS? code CL_ABAP_CHAR_UTILITIES=>HORIZONTAL_TAB doesn't work.
Many Thanks in advance
    LOOP at i_tab into wa_tab.
      REPLACE ALL OCCURRENCES OF CL_ABAP_CHAR_UTILITIES=>HORIZONTAL_TAB IN wa_tab WITH ','.
      WRITE /: wa_tab.
       MODIFY i_tab FROM wa_tab.
    ENDLOOP.

Hi,
    How you have passed values in GUI_UPLOAD FM
Check below link
CALL FUNCTION 'GUI_UPLOAD'
    EXPORTING
      filename                      = lv_file
*     FILETYPE                      = 'ASC'
     has_field_separator           = 'X'            " -----> Just set this flag and see in debugger after upload, values must be in required fields of Itab
*     HEADER_LENGTH                 = 1
*     READ_BY_LINE                  = 'X'
*     DAT_MODE                      = ' '
*     CODEPAGE                      = ' '
*     IGNORE_CERR                   = ABAP_TRUE
*     REPLACEMENT                   = '#'
*     CHECK_BOM                     = ' '
*     VIRUS_SCAN_PROFILE            =
*     NO_AUTH_CHECK                 = ' '
*   IMPORTING
*     FILELENGTH                    =
*     HEADER                        =
    TABLES
      data_tab                      = lt_ebidclt
   EXCEPTIONS
     file_open_error               = 1
     file_read_error               = 2
     no_batch                      = 3
     gui_refuse_filetransfer       = 4
     invalid_type                  = 5
     no_authority                  = 6
     unknown_error                 = 7
     bad_data_format               = 8
     header_not_allowed            = 9
     separator_not_allowed         = 10
     header_too_long               = 11
     unknown_dp_error              = 12
     access_denied                 = 13
     dp_out_of_memory              = 14
     disk_full                     = 15
     dp_timeout                    = 16
     OTHERS                        = 17
  IF sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
  ENDIF.
