Help needed with Dynamic Filtering for RANKX Function

BICrazy — Tue, 04 Jan 2022 19:56:28 GMT

Hi there Power BI Community,

I've hit a roadblock with regards to filtering whilst ranking a column

I have 3 Columns i.e. Countries, Region and Sub-Region which are each ranked by a value, which is working fine and gives me the ranking of the country:

However, when I filter the countries, what I'd like is for the region and sub-region not to default to 1.
Here is an example of the problem: I chose South Africa and region and Sub Region default to 1.

What I would like to ideally see when filtering by country e.g. if I choose South Africa, the Region should display Africa as 6 and Sub-Region as 3. Note that in the below image, I did not select South Africa. If I do select it, then the Region and Sub-Region change to 1.

Here are the measure's that I am using to perform the ranking of the 2 columns:
Sub-Region Ranking:

Sub Region Ranking = RANKX( ALLSELECTED( Country_Name[Sub-Region] ), CALCULATE( [Average Values WB]) ,,desc, Dense)

Region Ranking:

Region Ranking = RANKX( ALLSELECTED(Country_Name[Region] ), CALCULATE( [Average Values WB]) ,,DESC, Dense )

Country Ranking:

Country Ranking = RANKX( ALLSELECTED( Correct_Country_Spell[Country_Name]), CALCULATE([YoY% Change since 2010]) ,,desc, Dense )

Hope that I've provided sufficient information for assistance and thanks in advance.

Regards

If you don't want the rank to change in response to filters, then it sounds like you want static ranking rather than dynamic ranking, in which case you may want to define rank via calculated columns rather than measures.

Hi BICrazy

Try to use calculated columns rather than measures.

Hi, BICrazy

I agree with them, but here I see that you haven't replied. Have you solved the problem? If not, please share some insensitive data samples and expected output. In addition, we don't know the codes of these two measures: [YoY% Change since 2010] and [Average Values WB], you also need to explain.

Best Regards,

Hi there all,

Apologies for the delayed response. It's been a busy few weeks to the start of 2022...all Power BI related though 😊

I tried using calculated columns for this exercise but the model became too slow as the fact table contains approximately 13M row's and I had to create 3 columns, 1 for the country, 1 for the region, and another for subregion. These +/- 40 M iterations were causing the Power BI Desktop refreshes to timeout.

I then proceeded to build a model with measures using sample data which I tested and ended up working. I will post the solution shortly.
