以@olly（）&文件： pwrbi/so_55281950-2/

在示例文件中，将创建假设或场景分析。使用了两个切片器，一个切片器选择方案，另一个切片器选择对象以应用方案。 @Olly提供了一个聪明的解决方案来处理这种情况：

In the sample file a "what if" or scenario analysis is created. Two slicers are used, one which selects the scenario, and another one which selects the objects to apply the scenario on. @Olly provided a clever solution to deal with the situation:

Value + Trend = SUMX ( 'Demo Fact Table'; 'Demo Fact Table'[Value] * ( 1 + IF ( ISFILTERED ( 'Item Chooser'[Item] ) && CONTAINS ( 'Item Chooser'; 'Item Chooser'[Item]; 'Demo Fact Table'[Item] ) && HASONEVALUE ( 'Scenario - Trend'[Category] ); VALUES ( 'Scenario - Trend'[Trend Rise] ); 'Demo Fact Table'[trend_default] ) ) )

在此解决方案的基础上，我一直尝试应用相同的方法逻辑，但要解决我的特定问题。在我的问题中，我不仅有一层类别，而且还有3个层次的层次结构。 如果我的类别具有层次结构，我将如何继续应用相同的解决方案？因此，从我的切片器中，我将选择三项内容：Category1，Year和Category2，这将产生选择的Trend_rise。并将其应用到选定的（第4个切片器）行上，即对（项目A，B或/和C）行应用这一Trend_rise

Building upon this solution I've been trying to apply the same logic, but to my specific problem. In my problem I don't only have a single layer of "categories", but instead hierarchy of 3 levels. How would I go on about applying the same solution if my categories had hierarchies? So from my slicer I would select three things: Category1, Year and Category2, which would yield the trend_rise for the selection. and would apply this apply this trend_rise on the selected (4th slicer) rows, i.e. (item A,B or/and C)

category1 - Year - Category2 - trend rise POSITIVE-trends 2018 low 5% POSITIVE-trends 2018 high 5% POSITIVE-trends 2017 low 5% NEGATIVE-trends 2017 very high -5% NEUTRAL-trends 2018 low 0% POSITIVE-trends 2018 high 5% NEUTRAL-trends 2017 low 5% NEUTRAL-trends 2016 very high 15%

推荐答案

您只需要对度量进行一点调整即可检查 trend_rise 字段是否具有一个值，如果是，则使用该值，否则使用默认值：

You only need a small tweak to the measure, to check whether the trend_rise field has one value, and if so then use that, otherwise use the default:

Value + Trend = SUMX ( 'Demo Fact Table', 'Demo Fact Table'[Value] * ( 1 + IF ( ISFILTERED ( 'Item Chooser'[Item] ) && CONTAINS ( 'Item Chooser', 'Item Chooser'[Item], 'Demo Fact Table'[Item] ) && HASONEVALUE ( 'Scenario - Trend'[Trend Rise] ), VALUES ( 'Scenario - Trend'[Trend Rise] ), 'Demo Fact Table'[trend_default] ) ) )

现在您可以在所有列上使用切片器方案表。

Now you can use slicers on all columns of your Scenario table.
