Question

Power BI新手，但已下载Power BI Desktop。我把它连接到我的Postgres数据库，一切都很好看。我正在提取数据并能够开始建立关系＆amp;报告。

我看到这个奇怪的酒吧出现了：

我点击了它，看起来它连接到数据库并从我的所有表中再次提取数据。最后，我看到一条带有此警告的错误通知：

Failed to save modifications to the Server. Error returned: 'The base version must not be negative when impact is requested for a transaction.'.

它让我成为“复制详情”，我看到完整的堆栈跟踪：

Error Message:

Failed to save modifications to the Server. Error returned: 'The base version must not be negative when impact is requested for a transaction.
'.

Stack Trace:

Microsoft.AnalysisServices.OperationException: Failed to save modifications to the Server. Error returned: 'The base version must not be negative when impact is requested for a transaction.
'.

错误消息的含义是什么？我不知道哪些数据无法写出来。

此外，服务器尝试写入什么？它是否无法写入Power BI的本地内部数据库，或者是否尝试写入我的远程连接的postgres数据库？

我知道较早的帖子，但我刚收到此错误消息并能够解决它。

四处搜寻，我发现一个叫jagatho的用户this post

它与关系的自动检测有关。如果我删除了使Power BI可以预测表之间有关联的列，并在两个PowerQuery步骤中添加了一个新的同名且具有空值的列，那么就可以加载数据了。这两个步骤就可以了，因为它只尝试检测初始负载下的关系。

在Power BI Desktop（版本：2.64.5285.661 64位（2018年11月））中，我找不到导致问题的列，选项和设置|选项|当前文件|数据加载，取消选中“加载数据后自动检测新关系”对我来说解决了这个问题。
