根据其他列中的特定条件,使用Power BI创建特定列(标头和标头中的数据)

问题描述 投票:0回答:1

我首先从VBA开始,建议使用PowerBI。但是,我的问题是否真的可以通过powerBI解决。

我有一个定期发送的文件,其中包含需要分组的特定信息。我正在尝试创建一个VBA宏来自动执行文件准备,并使其适合于在其他工具中导入。

我大约有40个列,但有时更少。列的位置有时会更改,因此我无法参考列的位置(A,B,C ...),我必须寻找列的名称。

而且,我必须寻找一些特定的列。如果这些列中有数据,则需要将每种情况的特定元素添加到先前串联的列中。

我在下面提供示例代码

这里是虚拟数据描述:

|客户| ID |信息超人|信息产品类型|规格1 |规格2 |指定一个|规格b |信息客户类型|信息设施类型|地理|

[当“ spec 1”,“ spec 2”,“ Spec a”或“ Spec b”都没有值时,我需要按以下方式对数据进行分组(包括标题):“ Client” +“ Superman” + Bravo +“ Info顾客类型“ +信息设施类型”,即ClientSpermanBravoInfo

[如果有规格1或2的值:“客户端”“超人” AlphaBravo“信息客户类型”信息工具类型“

[如果规格1或2以及规格a和b有值:“客户”“超人” AlphaAlphaBravo“信息客户类型”信息工具类型“。

到目前为止,我具有以下VBA代码,但是使用PowerBI将提供一个更简单,更优雅的解决方案。我一直在寻找接近该资源的资源,例如:https://powerbi.microsoft.com/en-us/blog/power-bi-desktop-april-update-feature-summary/,以便以特定方式查询数据,并根据特定条件创建列,但是我找不到解决方案。

您的问题混合了各种列名,因此很难遵循(例如,没有名为“ spec”的列,例如,我们仅查看“ spec 1”,“ spec 2”,“ spec a”和“ spec b”)。
