How can I convert a space from ABAP to CSV data?

Question

Hello guys,
how can I convert a string like
"This is a%test%"
to
"This is  a test "
into CSV data?
I try to with   REPLACE ALL OCCURRENCES OF '%' IN string_above WITH space,
but I got the string without space, like
"This is  atest"
I read some posts that CSV will ignore space.
But which kind of symbol in CSV represents space?
Thanks for any suggestion!
Regards,
Liying

USE THE CODE AS SHOWN BELOW...
TYPES : BEGIN OF tp_data,
          line(4096),
        END   OF tp_data.
*&      Form  gui_upload
      Upload the data from the input file to the internal table
FORM gui_upload.
*--Local data declaration
  DATA: l_filename_ip TYPE string,
        tl_data       TYPE STANDARD TABLE OF tp_data WITH HEADER LINE.
  l_filename_ip = p_input.
*--Upload Data
  CALL FUNCTION 'GUI_UPLOAD'
       EXPORTING
            filename                = l_filename_ip
            filetype                = 'ASC'
            has_field_separator     = ''
       TABLES
            data_tab                = tl_data
       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 'S' NUMBER sy-msgno
            WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
    IF sy-subrc = 1.
      MESSAGE e000 WITH text-e04.
    ENDIF.
  ELSE.
    LOOP AT tl_data FROM 2.
*--Taking the contents of the input file leaving the header part
      PERFORM split_and_save USING tl_data-line.
    ENDLOOP.
  ENDIF.
ENDFORM.                    " gui_upload
*&      Form  split_and_save
      Splitting the contents from the input file and saving them into
      an internal table
     -->P_TL_DATA_LINE  text
FORM split_and_save USING fp_data.
*--Local data declaration
  DATA : tl_data TYPE STANDARD TABLE OF tp_data WITH HEADER LINE,
         l_type  TYPE c,
         c_space(1) TYPE c VALUE ' '.
*--Split at the Comma
  SPLIT fp_data AT c_space INTO TABLE tl_data.
  CLEAR inputtab.
*--Move it to the target fields
  DO.
    ASSIGN COMPONENT sy-index OF STRUCTURE inputtab TO <fs_field>.
    IF NOT sy-subrc IS INITIAL.
      EXIT.
    ENDIF.
*--Extract source data
    CLEAR tl_data.
    READ TABLE tl_data INDEX sy-index.
*--Populate the target
    <fs_field> = tl_data-line.
  ENDDO.
*--Append this record
  APPEND inputtab.
ENDFORM.                    " split_and_save
In the above code u can use make inputtab like tp_data and get the result as requires in an internal table as space seperated fields.
In place of space u can also use any other symbol.
And after that u can replace all occurences of space with the comma by using the statement that u have written below.
