Unicode Errors

Former Member — Thu, 21 May 2009 12:44:56 GMT

Hi ABAPpers,

I am getting the Unicode error as

Upload/Ws_Upload and Download/Ws_Download are obsolete, since they are not

Unicode-enabled; use the class cl_gui_frontend_services

in the below code

CALL FUNCTION 'UPLOAD'

EXPORTING

FILENAME = 'C:\'

FILETYPE = 'DAT'

IMPORTING

ACT_FILENAME = P_FILENAME

TABLES

DATA_TAB = I_FILE

EXCEPTIONS

CONVERSION_ERROR = 1

INVALID_TABLE_WIDTH = 2

INVALID_TYPE = 3

NO_BATCH = 4

UNKNOWN_ERROR = 5

OTHERS = 6.

CASE SY-SUBRC.

WHEN '1'. MESSAGE E014(ZV) WITH 'Conversion_error'.

WHEN '2'. MESSAGE E014(ZV) WITH 'Invalid_table_width'.

WHEN '3'. MESSAGE E014(ZV) WITH 'Invalid_type'.

WHEN '4'. MESSAGE E014(ZV) WITH 'No_batch'.

WHEN '5'. MESSAGE E014(ZV) WITH 'Unknown_error'.

WHEN '6'. MESSAGE E014(ZV) WITH 'Others'.

ENDCASE.

Now I want to chage the function module UPLOAD to GUI_UPLOAD but the problem is importing parameter ACT_FILENAME is not their in GUI_UPLOAD.

How to correct this error.

Please Reply.

Thanks and Regard,

Rahul Sinha

Hi,

UPLOAD function module automatically provides a popup which is not available with GUI_UPLOAD. You have to use 2 methods. Here is a example

After File open dialog the valiable W_P_FILE will be same as ACT_FILENAME and W_P_FILE will be used in GUI_UPLOAD

DATA : I_FILE_TABLE TYPE  TABLE OF FILE_TABLE, 
       W_FILETABLE  TYPE  FILE_TABLE,
       W_RC         TYPE  I,
       W_P_FILE     TYPE  STRING,
       prc_user_action TYPE I.
CONSTANTS: C_ASC(10)  TYPE  C VALUE 'ASC'. 

  W_P_FILE =  'C:\'.
     CALL METHOD CL_GUI_FRONTEND_SERVICES=>FILE_OPEN_DIALOG
       EXPORTING
*         WINDOW_TITLE            =
*         DEFAULT_EXTENSION       =
          DEFAULT_FILENAME        = W_P_FILE
*         FILE_FILTER             = 
*         WITH_ENCODING           =
*         INITIAL_DIRECTORY       =
*         MULTISELECTION          =
       CHANGING
          FILE_TABLE              = I_FILE_TABLE
          RC                      = W_RC 
          USER_ACTION             = prc_user_action
*         FILE_ENCODING           =
       EXCEPTIONS
         FILE_OPEN_DIALOG_FAILED = 1
         CNTL_ERROR              = 2
         ERROR_NO_GUI            = 3
         NOT_SUPPORTED_BY_GUI    = 4
         others                  = 5      .
     IF sy-subrc = 0
  AND prc_user_action NE 
  CL_GUI_FRONTEND_SERVICES=>ACTION_CANCEL.
 LOOP AT I_FILE_TABLE INTO W_FILETABLE.
  W_P_FILE = W_FILETABLE-FILENAME.
  EXIT  .
 ENDLOOP.

Hi ,

WS_UPLOAD , UPLOAD etc. function modules are obsolete.

So use the GUI_UPLOAD and GUI_DOWNLOAD of the class

cl_gui_frontend_services , that issue will be relosved

Check the code - -

CALL METHOD cl_gui_frontend_services=>gui_upload " To upload the file into int. table
  EXPORTING
    FILENAME                = 'C:\' " Specify the full file path
*    FILETYPE                = 'ASC'  " Specify the desired file type
*    HAS_FIELD_SEPARATOR     = SPACE
*    HEADER_LENGTH           = 0
*    READ_BY_LINE            = 'X'
*    DAT_MODE                = SPACE
*    CODEPAGE                = SPACE
*    IGNORE_CERR             = ABAP_TRUE
*    REPLACEMENT             = '#'
*    VIRUS_SCAN_PROFILE      =
*  IMPORTING
*    FILELENGTH              =
*    HEADER                  =
  CHANGING
    data_tab                = I_FILE " Internal table where data will be uploaded
  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
    NOT_SUPPORTED_BY_GUI    = 17
    ERROR_NO_GUI            = 18
    others                  = 19
        .
IF sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*            WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.

Similarly use the gui_download of class cl_gui_frontend_services to download

the the contents of the internal table to a file of presentation server.

CALL METHOD cl_gui_frontend_services=>gui_download
  EXPORTING
*    BIN_FILESIZE              =
    filename                  = 'C:\' " Specify the fine name with path
*    FILETYPE                  = 'ASC'
*    APPEND                    = SPACE
*    WRITE_FIELD_SEPARATOR     = SPACE
*    HEADER                    = '00'

      .
      .
      .
  changing
    data_tab                  = i_file " Internal table that contains the data
  EXCEPTIONS
    FILE_WRITE_ERROR          = 1
    NO_BATCH                  = 2
   .
   .
