我遇到了以前从未遇到过的问题。我已经构建了一个包含4个结果对象的派生表，根据Universe Designer，它可以正常工作。表和所有4个对象都已成功解析，当我通过表值选项运行表时，它完全符合我的预期，完全符合我们的前端报告的数据。到现在为止还挺好。
我遇到的问题是Webi。当我将该表中的任何对象引入新报表并运行它时，我收到以下错误：
A database error occured. The database error text is: ORA-00903: invalid table name. (WIS 10901)
这怎么可能？当我在Webi中使用该对象时，Universe Designer和我认为我们的Oracle数据库都说工作正常并返回数据的对象怎么能给我这个错误？我重建了表格，重新检查所有表格名称并缩短它们以防万一，任何表格名称都没有不寻常的字母数字字符，我还能做什么？这是在Universe中工作的代码，在WebI中失败：

我不知所措。发生了什么，我错过了什么？
