Chart Drilldown - Using different data sources at each level

[Anonymous]

I am working from a table which has the below structure:

I would like to create a drilldown visual where each layer looks at the total numeric value based on that selection. For example:

• Top layer is National 1 and it shows total numeric value for national_1 data level
• User drills down in the visual to England (national_3) and I would then want total numeric value for data level 'national_3' to be applied for where 'National_3' = England
• User then drills down into Regions within England and I would then want total numeric value for data level 'region' where 'national_3' = England
• And then so on...
• The data hierarchy is (top to bottom level) - National_1 -> National_3 -> Region -> County -> Local Authority
• I am unable to SUM from the lowest value as SUM local authority doesn't equal the total value in County. Each 'data_level' looks at a different source data

I would really appreciate some help on this, I have been stuck on this problem all week.

Hi  @Anonymous thank you for responding. Unfortunately your meothod doesn't work. Here is a link to my sample dataset -

The blow is the measure which I created which almost appears to work

RETURN

SWITCH(TRUE()

----COUNTRY

,HASONEVALUE(Consolidated_LLMIT[national_3]) && HASONEVALUE(Consolidated_LLMIT[region]) = FALSE(),

CALCULATE(SUM(Consolidated_LLMIT[numeric_value]),Consolidated_LLMIT[data_level] = Consolidated_LLMIT[national_3])

----REGION

,HASONEVALUE(Consolidated_LLMIT[region]) && HASONEVALUE(Consolidated_LLMIT[county]) = FALSE(),

CALCULATE(SUM(Consolidated_LLMIT[numeric_value]),Consolidated_LLMIT[data_level] = Consolidated_LLMIT[region])

----COUNTY

,HASONEVALUE(Consolidated_LLMIT[county]) && HASONEVALUE(Consolidated_LLMIT[local_authority]) = FALSE(),

CALCULATE(SUM(Consolidated_LLMIT[numeric_value]),Consolidated_LLMIT[data_level] = Consolidated_LLMIT[county])

----LOCAL AUTHORITY

,HASONEVALUE(Consolidated_LLMIT[local_authority]),

CALCULATE(SUM(Consolidated_LLMIT[numeric_value]),Consolidated_LLMIT[data_level] = Consolidated_LLMIT[local_authority])

Hi @Anonymous ,

You can use the "Drilldown" feature in Power BI.

Please have a try.

Here are the steps you can follow:

1. Create a new visual in Power BI and add the relevant data fields to the visual.

2. Click on the "Drilldown" button in the visualizations pane.

3. In the "Drilldown" pane, select the hierarchy you want to use for the drilldown. In your case, this would be the hierarchy from National_1 to Local Authority.

4. Click on the "Apply" button to apply the drilldown hierarchy to the visual.

5. Now, when you click on a data point in the visual, it will drill down to the next level in the hierarchy and show the total numeric value for that level.

6. To show the total numeric value for each level in the hierarchy, you can add a "Total" column to your data table and use the "SUM" function to calculate the total for each level.
