GUI_DOWNLOAD - columns misplaced in excel

Question

1.As per my requirement the user want the report to displayed in excel without displaying on the screen.So the user enters the path where they want this report to be downloaded in the select option screen.
2.We are using the function module GUI_DOWNLOAD to display output in excel.
3.There is one problem related to output display. The columns for some materials are getting skewed or misplaced.
4.I have tried all combinations of export perameters in GUI_DOWNLOAD but still not able to find the cause for this skewing of data.
Here is the code that i have used to display.
CALL FUNCTION 'GUI_DOWNLOAD'
      EXPORTING
        filename                = pa_dwfil
        filetype                = 'ASC'
        append                  = 'X'
        write_field_separator   = 'X'
        header                  = '00'
        codepage                = lv_codepage
      TABLES
        data_tab                = <dyn_table>
        fieldnames              = gt_inthead
      EXCEPTIONS
        file_write_error        = 1
        no_batch                = 2
        gui_refuse_filetransfer = 3
        invalid_type            = 4
        no_authority            = 5
        unknown_error           = 6
        header_not_allowed      = 7
        separator_not_allowed   = 8
        filesize_not_allowed    = 9
        header_too_long         = 10
        dp_error_create         = 11
        dp_error_send           = 12
        dp_error_write          = 13
        unknown_dp_error        = 14
        access_denied           = 15
        dp_out_of_memory        = 16
        disk_full               = 17
        dp_timeout              = 18
        file_not_found          = 19
        dataprovider_exception  = 20
        control_flush_error     = 21
        OTHERS                  = 22.
    IF sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
    ENDIF.
My material description has '#' symbol within it. So I used to remove '#' symbol by using REPLACE ALL as follows,
REPLACE ALL OCCURRENCES OF '#' IN wa_itab-maktx WITH ' '.
It is working fine in D system. But Replace fails in Q system.
Any help is greatly appreciated

Answer 1

You are right. I got the hexadecimal value is 09 for desc whenever it has '#' symbol.
To resolve this,
REPLACE ALL OCCURRENCES OF CL_ABAP_CHAR_UTILITIES=>HORIZONTAL_TAB IN wa_itab-maktx WITH ' '.
or
REPLACE ALL OCCURRENCES OF CL_ABAP_CHAR_UTILITIES=>CR_LF IN wa_itab-maktx WITH ' '.
or
REPLACE ALL OCCURRENCES OF CL_ABAP_CHAR_UTILITIES=>NEWLINE IN wa_itab-maktx WITH ' '.
From the above which one i need to be used.
Because i read many posts in this forums. They said the above code for the same issue with '#' symbol.
Can you help me out to solve this.
