Hello,

U can use WS_DOWNLOAD like this:


L_T_HEADERS TYPE TABLE OF TEXT40.
IF SP_LOCAL = 'X'.
* Headings: TEXT-U01 ... TEXT-U28
    DO 28 TIMES.
      CLEAR: L_F_INDEX,L_F_NAME,L_F_HEADERS.
      L_F_INDEX = SY-INDEX.
      CONCATENATE 'TEXT-U' L_F_INDEX INTO L_F_NAME.
      ASSIGN (L_F_NAME) TO <FS_HEADER>.
      L_F_HEADERS = <FS_HEADER>.
      APPEND L_F_HEADERS TO L_T_HEADERS.
    ENDDO.

    CALL FUNCTION 'WS_DOWNLOAD'
         EXPORTING
              FILENAME                = SP_FILE
              FILETYPE                = 'DAT'
         TABLES
              DATA_TAB                = L_T_OUT
              FIELDNAMES              = L_T_HEADERS
         EXCEPTIONS
              FILE_OPEN_ERROR         = 1
              FILE_WRITE_ERROR        = 2
              INVALID_FILESIZE        = 3
              INVALID_TYPE            = 4
              NO_BATCH                = 5
              UNKNOWN_ERROR           = 6
              INVALID_TABLE_WIDTH     = 7
              GUI_REFUSE_FILETRANSFER = 8
              CUSTOMER_ERROR          = 9
              OTHERS                  = 10.

    IF SY-SUBRC <> 0.
      MESSAGE ID SY-MSGID TYPE 'I' NUMBER SY-MSGNO
              WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
      LEAVE PROGRAM.
    ELSE.
      DESCRIBE TABLE L_T_OUT LINES L_F_COUNT.
      MESSAGE I145 WITH L_F_COUNT SP_FILE.
    ENDIF.

The fieldnames table doesn't work in this function. If you define all your fields as text, you can insert headers as the first row in the data table.
