Top N selection based on filter

[Anonymous]

I have a query regarding the Top N filter.

I have a table in PowerBI which I want to split (when exported to Powerpoint the whole table is not exported).

So I decided to provide a slicer on top for Top N (in-between) values. So that the user can manually set the values in between them. 

I have created a TOP N column as mentioned below:

Top N = RANKX(carrier_attributes,carrier_attributes[Carrier Name],,DESC,Dense)

which is giving me the output for the TOP N based on Column [Carrier Name]. 

But now the challenge is when the user is selecting a specific Column [Carrier Name] filter (which is a different filter) the TOP N filter is not getting updated.

I have a total of 350 entries, but when I select a specific customer For Eg. WNS GLOBAL SERVICES which only have 17 entries. The RANK filter is not getting updated to 1-17 (shown in image)

I expect the output of N entries when a specific Carrier Name with N entries is selected, i.e. the TOP N dynamically changing with Column [Carrier Name] filter

Hi

Columns in PowerBI are unaffected by slicers because they are pre-calculated when the dataset is refreshed. You will need to use a measure for this.

I created a measure based on carrier_attributes[Call Limit]:

Rank = RANKX(ALL(carrier_attributes),SUM(carrier_attributes[Call Limit]),,DESC)

But I think Measure cannot be used in a slicer. I want to display the number in a slicer so that the user can dynamically select the data and export the ppt.

hi, @Anonymous 

First, you should know that calculated column and calculate table can't be affected by any slicer. you could create a measure instead of column.
Notice:
1. Calculation column/table not support dynamic changed based on filter or slicer.
2. Measure can be affected by filter/slicer, so you can use it to get dynamic summary result.
here is reference:

https://www.sqlbi.com/articles/calculated-columns-and-measures-in-dax/

Second, based on your measure, you could add a what if parameter as a slicer.

Then add a measure

TopN = IF([Rank]<=[Parameter Value],[Rank])

Here is a simple sample pbix file,  please try it.

By the way, your measure 

Rank = RANKX(ALL(carrier_attributes),SUM(carrier_attributes[Call Limit]),,DESC)

 is wrong, if this rank measure could meet you.

Rank = RANKX(ALLSELECTED(carrier_attributes),CALCULATE(SUM(carrier_attributes[Call Limit])),,DESC)
