python使用SAP GUI操作SAP的几个坑

1) 首先必须设定SAP中设置可以使用SAP GUI Script.

详细参见以下文章:

https://blog.csdn.net/weixin_44447687/article/details/106216776

简单来说就是 SAP ==>RZ11==>sapgui/user_scripting==>需要设定为true

需要设定为  启用脚本==>下面的两个警告勾勾去掉(否则会出现不需要的弹窗)

2) 需要安装pywin32

   pip install pywin32

3) 录制Script

4) Python基本代码如下

    flt=0

    while flt==0:

            flt=win32gui.FindWindowEx(hwnd,None,"Edit", None)  #capture handle of filter

        except:

            time.sleep(0.5)

    session.findById("wnd[0]").sendVKey(0)
