I have a Power BI dataset as a data source in Power BI Report Builder. I have use DAX expression to generate the parameter as shown below:
EVALUATE SUMMARIZECOLUMNS('DimensionList'[TopLevel], 'DimensionList'[SubLevel], 'DimensionList'[Dimension], RSCustomDaxFilter(@DimensionListTopLevel,EqualToCondition,[DimensionList].[TopLevel],String), RSCustomDaxFilter(@DimensionListSubLevel,EqualToCondition,[DimensionList].[SubLevel],String), RSCustomDaxFilter(@DimensionListDimension,EqualToCondition,[DimensionList].[Dimension],String))
However, this is not cascading parameter. How can I rewrite this to cascade from TopLevel to SubLevel and finally Dimension?
