abap excel下载

ABAP可以通过使用函数模块GUI_DOWNLOAD将数据从SAP系统下载到Excel中。具体步骤如下：

1. 在ABAP程序中定义一个内表，将需要下载的数据存储在内表中。
2. 使用函数模块GUI_DOWNLOAD将内表中的数据下载到本地计算机上的Excel文件中。

以下是一个简单的示例代码：

DATA: itab TYPE STANDARD TABLE OF mara,
      filename TYPE string,
      path TYPE string.

SELECT * FROM mara INTO TABLE itab.

filename = 'example.xlsx'.
path = 'C:\Downloads\'.

CALL FUNCTION 'GUI_DOWNLOAD'
  EXPORTING
    filename = filename
    filetype = 'ASC'
    write_field_separator = 'X'
    append = ' '
  TABLES
    data_tab = itab
  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.
