Question

在M的以下查询中获取错误消息，我尝试在合并步骤之前拆分为2个不同的查询，但仍收到“此操作无法直接访问数据源，请重建数据组合”错误

*let
    Source = #"Query List from SP",
    cols = if {"Type"} = "Indicator" then 4 else 5,
    DataLoad = (path) =>

Answer 1

由于要链接到查询#"Query List from SP"，因此不会直接访问数据源。

有关此主题的文章很多。克里斯·韦伯（Chris Webb）拥有与数据隐私设置有关的整个blog series，但是摆脱此问题的最简单方法是简单地忽略隐私级别。

转到文件菜单下的选项和设置：

在“隐私”部分下，选择忽略隐私级别：

很显然，如果您要构建一些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，当隐私级别无关紧要时，这是一个简单方便的解决方法
