【问题描述】：

在 M 中获取以下查询的错误消息，我尝试在合并步骤之前拆分为 2 个不同的查询，但仍然收到“这不直接访问数据源，请重建数据组合”错误

    Source = #"Query List from SP",
    cols = if {"Type"} = "Indicator" then 4 else 5,

【解决方案1】：

您没有直接访问数据源，因为您链接到查询#"Query List from SP"。

关于这个主题已经写了很多。 Chris Webb 有一个完整的blog series 与数据隐私设置相关，但摆脱这个问题的最简单方法是简单地忽略隐私级别。

进入文件菜单下的选项和设置：

在隐私部分选择忽略隐私级别：

显然，如果您正在构建需要仔细管理隐私级别的东西，那么这是错误的方法，您需要更加小心。但是当隐私级别不是问题时，这是一个简单方便的解决方法
