经过几天的努力终于顺利的在windows 2000 sp4上装上了SAP 4.71现在把经验与大家分享一下
1）SAP硬件的要求比较高1G内存的情况下安装要8小时左右运行时加上客户端的内存需求，你所剩下的可能不到10兆。
安装时如果你只有80G硬盘建议只分一个区，应为你的安装软件要复制到硬盘同一目录后解压缩后才可以安装，这样安装好后你可能在不删除安装程序的情况下只有200兆左右的剩余了，在空间不足的情况下会出现这种错误

2）安装ides数据库，最后出现一个修改ddic用户密码的对话框，
安装程序运行了大约2分钟，也许会出现错误，4.7就是这德性。不用管，直接可以用了。此时密码为19920706 这是默认密码。此时安装状态列表处在这一行：
change ABAP User Passwords
安装进度条下面显示：
Changing DDIC password...
按错误提示框的view log按钮，结尾部分内容如下：
