How do I rank inside many segments?

[Zerozinho]

Hey, I'm not experienced with PowerBI and I'm failing to rank the following data:

Name	Group	Segment	Value	Rank	Max Rank
Jorge	1	Small	9	1	1
Jorge	1	Medium	9	1	2
Gabriel	1	Medium	8	2	2
Maria	2	Small	4	3	3
Maria	2	Medium	4	1	1
Maria	2	Big	5	1	1
Carlos	2	Small	6	2	3
Anthony	2	Small	7	1	3
Louis	3	Big	3	1	1

So, what I want to do is rank those values according to their Group and Segment (column Rank). I also would like to set another column with the number of contestants in each Group-Segment, set as "Max Rank".

I've tried using the RANKX function but I got no luck. Could someone can light me a solution for this problem, please?

Hi @Zerozinho ,

You can use this DAX expression to Rank groups and segments.

Ranki = RANKX(FILTER(ALL('Table'),'Table'[Segment] = MAX ('Table'[Segment]) && 'Table'[Group] = MAX ('Table'[Group])),CALCULATE(Sum('Table'[Value])))

For MAX Rank you can use the following DAX

Counti = COUNTX(FILTER(ALL('Table'),'Table'[Segment] = MAX ('Table'[Segment]) && 'Table'[Group] = MAX ('Table'[Group])),CALCULATE(Sum('Table'[Value])))

Thank you very much! It worked just fine!

Another question, do you have any idea of how to do the column "Max Rank", that just collect the number of rows in each "peer group" and set it as the Max Rank column in my example?
