bapi ‘BAPI_DOCUMENT_CREATE2‘可以模拟前台的tcode CV01N创建文档。
CV01N 前台操作，简单介绍如下:
输入document，type，part 和version相关内容，回车进入下一屏幕，
![创建文档[BAPI_DOCUMENT_CREATE2]](http://www.baidusap.com/wp-content/uploads/2017-02-07_13-09-53.png "创建文档[BAPI_DOCUMENT_CREATE2]")
输入描述，设置status和authorization group，然后点击保存即可。
![创建文档[BAPI_DOCUMENT_CREATE2]](http://www.baidusap.com/wp-content/uploads/2017-02-07_13-12-37.png "创建文档[BAPI_DOCUMENT_CREATE2]")
下面是模拟上述操作的例子代码：
