导出SAP表结构到EXCEl

将SE11中看到的数据表结构，制作成EXCEL文件，以便查阅。CPOY的话得一个字段一个元素的COPY再一个个粘过去，不仅麻烦，如果一个结构有上百个元素，工作量也是很大的。

研究整理了一下各位达人的程序，写了一个新的导出程序。本程序只需在选择界面输入要导出的结构名及保存路径，就在该路径下生成一个以该结构命名的EXCEL文件。也可以指定输出结构的单独字段。代码如下：

REPORT  YTABLE no standard page heading
                 message-id y2
                 line-size  200
                 line-count 65 .

tables: dfies, x030l,rlgrap.

data: begin of itab occurs 0.
        include structure dfies.
data: end of itab.
data: g_file like rlgrap-filename.   "下载保存路径
data:begin of itab1 occurs 0,
     fieldname like dfies-fieldname,  "Fieldname
     keyflag(4),    "KEY
     rollname(12),   "Data Element
     datatype(8),   "Data Type
     leng(6),       "Length
     decimals(6),   "Decimal Place
     fieldtext like dfies-fieldtext,  "Short Description
end of itab1.

本人是个菜鸟，写得不好望高手指点一二。
