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...

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)
