本文介绍了使用ABAP进行文件处理的方法，包括在网络盘中保存文件时指定UTF-8编码，下载文件时设置分隔符为Tab，以及如何在本地环境中保存文件。此外，还提供了一个ABAP程序示例，展示了如何实现这些操作。

网络盘中保存文件：* 直接使用 UTF-8

*    open dataset gv_file_6040 for output in text mode encoding default.
    open dataset gv_file_6040 for output in text mode encoding UTF-8 WITH BYTE-ORDER MARK
      WITH SMART LINEFEED.

    loop at itab_file_6040.
      condense itab_file_6040-line.
      transfer itab_file_6040-line to gv_file_6040.
    endloop.

close dataset gv_file_6040.

下载本地，并使用 UTF-8 格式

    CALL FUNCTION 'GUI_DOWNLOAD'
          EXPORTING
            CODEPAGE                      = '4110'
            FILENAME                      = file_name
            FILETYPE                      = 'ASC'
            WRITE_BOM                     = 'X'
          TABLES
            DATA_TAB                      = itab
          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

            OTHERS                        = 17.

下载文件时使用 TAB 分隔：

concatenate wa_ind
itab-vbeln
itab-qnum

                   ITAB-ZPROJ_STS
                 into itab_file_5020 separated by
                 cl_abap_char_utilities=>horizontal_tab.

本地保存文件：

*&---------------------------------------------------------------------*
*&      Form  download_local
*&---------------------------------------------------------------------*
form download_local.
  read table itab_file2 index 1.
  if sy-subrc eq 0.

    call function 'WS_DOWNLOAD'
      exporting
        filename                      =  gv_file
        filetype                      = 'ASC'
      tables
        data_tab                      = itab_file2
     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.
    endif.
  endif.
