ALTER TABLE is not possible

在DDIC中修改某个表的字段的数据类型时出现在此错误, 可以使用SE14来调整数据库.

 

另外这几天重新装了下系统,发现输入字段的历史没有了, google了一下, 说是SapWorkDir下的SAPHistory文件不存在,会影响到本地历史. 另外查看

C:\Documents and Settings\admin\SapWorkDir 中的跟踪文件发现有

(Error)(05.05.10 16:28:29.546): CSapHistoryDb::OpenDB: Could not create connection: -2147221164
Error                       : Loading local DB failed in frontend.

查了下Note, 需要修复安装MDAC.

右击在C:\WINDOWS\inf\mdac.inf  安装相关的dll文件. 注意此处需要windows 安装盘

参考:

sapnote_0000199527 Input history for SAP GUI for Windows

sapnote_0000931540 History: repair MDAC installation
