DAX TOPN - Get top 5 count from split by values of another column

janinw — Sat, 12 Dec 2020 11:35:21 GMT

Dear all,

I am struggling with the following:

I have a table with several columns: 'date', 'ticket_id', 'reason_group', 'reason_specific'.

What I want:

Get the top 5 reasons from the column 'reason_specific'
Based on the distinct count of the column 'ticket_id'
Then use this top 5 as a filter for a visual

So, the first 5 reasons of the table below should be the filter for a visual.

I am getting really lost with the TOPN, CALCULATE, CALCULATETABLE, SUMMARIZE.

Best,
Janine

Please find below the measure:

Top 5 Reason = var __rank = RANKX ( CALCULATETABLE ( SUMMARIZE ( Sheet1, Sheet1[reason_specific_en] ), ALLSELECTED ( Sheet1) ), CALCULATE ( DISTINCTCOUNT ( Sheet1[ticket_id] ) ), , DESC, DENSE ) return IF( __rank <= 5 , DISTINCTCOUNT ( Sheet1[ticket_id] ) )

Hi all,

I have realised an easy way of getting where I want is by doing the following:

Create a measure that calculates the % (or number) for reason_specific:
perc_tickets = divide(distinctcount([ticket_id]), calculate(distinctcount([ticket_id]), all([reason_specific])))
Then use the Top N filter type in PowerBI desktop.

Fowmy - your solution did not help in using it as a filter for a visual unfortunately. I had done similar things before, but that does not get me to what I want to do with it.
