Hi, how do you do a percentage off of two fields in the matrix grouping?
In this example, you see the totals here and I'm looking to do a [data changes] / [assessments administered] but every formula I've tried, including a simple [data changes] / [assessments administered] gives me incorrect results.
How would I go about creating a formula to show % (it seems so simple to do but wow, what a challenge it's been!)
In my grouping the following:
Row: User Name
Columns: Assessments Type
Values: Assessments Administered
Data Changes
Solved! Go to Solution.
Hi, @Anonymous
Based on what I've gotten, it seems to add up all the calculated percentages to get the total.
Please try using a measure like this:
Measure =
DIVIDE ( SUM ( [Data Changes] ), SUM ( [Assessments Administered] ) )
If it doesn't work, please share your sample pbix file's link here, then I can try to look into it to come up with a more accurate measure.

Thanks so much _ Zeon Zheng! It was the answer to my question and because of it i was able to finally take my complete my report and hand it over to validation! You are my hero!
@Anonymous Can you share sample data and sample output in table format? Or a sample pbix after removing sensitive data.
if these are measures
This should world
divide( [data changes] ,[assessments administered])
Hi amitchandak. thanks for your help so far. I tried to use the divide command but it didn't work.
Maybe here's a better example.
When I use a drilldown, the calculation works great on the detail, but in the totals in the same calculation, the result is different
For example, the calculation is simple here :Data Changes/Assessments Administered
when drilling down through alice rater, you see the % detail correctly under alice.rater,but when you look at the top data point you see the calculation is incorrect.
So my question is, why is the aggregation wrong and how would I fix that? I think that is where the solution lies.
