基于切片器选择在 Power BI 中创建动态计算表

Question

I'm new to Power BI. Currently facing similar issue explained below in my product development.

I have created power bi modle with below dimensions and facts from adventureworksDW.

Then I created a calculated table, which gives result as sum of sales group by ProductSubCategory and ProductCategory. Below is the DAX for the calculated table.

Now I want to create a new calculated table, which gives me TOPn ProductSubCategory based on the Total sales amount. Below is the DAX to do this.

and model relationships looks like below.

I want this TOPn rows to be displayed based on filter condition on product category. Something like below.

This works fine when I hardcode the product category value in the DAX itself. But if I want to change this product category values from the slicer selection, then I didn't get any results.

Answer 1

What you are asking for is not possible as Power BI is currently designed. Slicers cannot affect calculated tables. Calculated columns and calculated tables are evaluated once when the data is first loaded and are static until the data is refreshed.

However, you can get the table visual you want in a much simpler manner by writing the appropriate measure and putting that in the table instead of defining an entirely separate table.

TotalSales = SUM(FactInternetSales[SalesAmount])

The Top N filtering is available in the visual level filters settings.

Answer 2

You can simply use the SELECTEDVALUE function as shown below.

var __SelectedValue = SELECTEDVALUE('ProductSales'[EnglishProductCatogaryName])
return
Filter(
    'ProductSales',
    'ProductSales'[EnglishProductCatogaryName] = __SelectedValue 
    )
)

Answer 3

thanks for the reply.

As you suggested, I know that I can get TopN Product Sub Category values by creating appropriate measures and without creating entirely separate calculated table.

And it is possible to get only TopN results by creating a visual filter.

Issue is resolved. :) .

But my requirement is different. Based on the top 3 Product Sub Categories from the above result, I want to create 3 different visuals/charts in the report dynamically. Something like below.

enter image description here

Here I have applied visual filter manually for 3 different charts.

enter image description here

I want this visual filter to be applied dynamically. That is when I select “Bikes” Product Category from the slicer then these 3 charts visual filter to be dynamically applied for top 3 Product Sub Categories of “Bikes”. Now, when I select “Bikes” Product Category from the slicer, these 3 charts will show results like below. :( .

enter image description here

To achieve this requirement, I thought dynamic calculated table will help me, which will give always give top 3 Product Sub Categories based on my Product Category slicer selection.

Hope, now my requirement is clear!!

Please suggest if there is any workaround or alternate approach to get result for my requirement.

Thanks in advance.
