FM - gui_upload. Problems uploading CSV format file

Question

Hi experts,
I am facing an issue here. I tried to upload a .csv format file using FM - gui_load, in the table LT_RAW all the information is all in one column and rest of the columns are empty.
How can i get the information to its respective fields?
below are my codes:
CALL FUNCTION 'GUI_UPLOAD'
    EXPORTING
      filename                = pv_file
      READ_BY_LINE            = 'X'
      HAS_FIELD_SEPARATOR     = 'X'
      codepage                = '4110'
    IMPORTING
      filelength              = lv_filelength
    TABLES
      data_tab                = lt_raw
    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.
I can only upload using .CSV format.

Hi Suhas,
below is the new code that i used. now the data is not filled in only one column,
Instead it will fill up the max length of the field and continue the data in other field and fill up its max length of the field.
" my declaration of lt_raw and ls_raw
lt_raw            TYPE TABLE OF ZCTD_MIGCUSTOMER,
ls_raw            like line of lt_raw,
CALL FUNCTION 'GUI_UPLOAD'
    EXPORTING
      filename                = pv_file
      codepage                = '4110'
    IMPORTING
      filelength              = lv_filelength
    TABLES
      data_tab                = lt_raw
    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.
