Need Help: Dynamic Filtering in Power BI: Show All Relevant Items Beyond Initial Top 8

[BaSan]

Hello everyone,

I am seeking a help. 

I am building a Power BI report on closed project details since 2000, with visuals organized by:

1. Closed projects by Year
2. Closed projects by Region
3. Closed projects by Country (Top N filter applied)
4. Closed projects by Sector (Top N filter applied)

I am using the Top N feature for the Country and Sector visuals to initially display only the top 8 items by project closed counts.

Challenge: Currently, if I click on a specific Country (e.g., Brazil), the Sector visual still only displays the sectors within the top 8 list, rather than dynamically updating to show all sectors in Brazil. I need the Sector visual to display all sectors associated with the selected country, not just those that were in the original Top 8.

Likewise, if I click on a sector, I want the Country visual to display all relevant countries involved in that sector, even if they were not in the initial Top 8 list.

Goal: 

• When I select a country, the Sector visual dynamically shows all sectors associated with that country.
• When I select a sector, the Country visual dynamically shows all countries associated with that sector.

Essentially, I want the cross-filtering to override the initial Top N filter, showing all relevant items associated with the selection, not just those in the Top 8.

If anyone has suggestions or a workaround to achieve this dynamic, context-sensitive filtering, I would really appreciate your help!

Thank you!

Hi @BaSan ,

Here I create a sample to show you how to achieve your goal. I think you can try ISFILTERED() and IF() function.

Dynamic TopN for Country = 
VAR _TopN =
    IF (
        MAX ( 'Table'[Country] )
            IN SUMMARIZE (
                TOPN (
                    8,
                    SUMMARIZE (
                        ALLSELECTED ( 'Table' ),
                        'Table'[Country],
                        "Count", CALCULATE ( SUM ( 'Table'[Value] ) )
                    ),
                    [Count], DESC
                ),
                [Country]
            ),
        1,
        0
    )
RETURN
    IF ( ISFILTERED ( 'Table'[Country] ), 1, _TopN )

Dynamic TopN for Sector = 
VAR _TopN =
    IF (
        MAX ( 'Table'[Sector] )
            IN SUMMARIZE (
                TOPN (
                    8,
                    SUMMARIZE (
                        ALLSELECTED ( 'Table' ),
                        'Table'[Sector],
                        "Count", CALCULATE ( SUM ( 'Table'[Value] ) )
                    ),
                    [Count], DESC
                ),
                [Sector]
            ),
        1,
        0
    )
RETURN
    IF ( ISFILTERED ( 'Table'[Country] ), 1, _TopN )

Add above measure into Country/Sector visual and set it to show items when value  = 1.

Since I have less data in my sample, I show Top1. So when by default it will show Top1 in Country/Sector visual.

When I select C3 in country, the Sector visual will show all sector in this coutry.

When I select S2 in Sector, the Coutry visual will show all country in this sector.

Hi @BaSan  It is better to provide dummy data and your expected result to accurate solution.

The TOPN function is used to return the top N rows of a table based on a specified expression. It is more static and does not dynamically adjust based on user selections. When you apply a TOPN filter, it limits the data to the top N items based on the initial criteria, and this filter remains fixed unless manually changed.

However, I would like to suggest first rank country and sector and then evaluate top country and sector. You could try this method:

CountryRank = RANKX(ALL('Table'[Country]), CALCULATE(SUM('Table'[ClosedProjects])), , DESC, DENSE)
SectorRank = RANKX(ALL('Table'[Sector]), CALCULATE(SUM('Table'[ClosedProjects])), , DESC, DENSE)

and Top:

top8Country = IF(CountryRank <= 8, 1, 0)
top8Sector = IF(SectorRank<= 8, 1, 0)

Place this measure in filter this visual section and set value to 1. This way, when you select a country or sector, the visuals update to show all relevant items, not just the top N.


Hope this helps!!
