Aggregation of Distinct Count Measure

[rrwprioste]

Hello,

I need to count how many teams have only one city associated with at least one employee. My data set has many columns, but the relevants for this case are the following:

Team         City             Employee

A            Shanghai              3

A               Beijing               5

B               Helsinki             1

B               Beijing               0

C              Berlin                 10

D              Shanghai            5

D                Berlin                6

In the example above this count would be 2 (B and C), and I managed to create a measure that counts how many associated cities each team has using:

# of Cities = CALCULATE(DISTINCTCOUNT(Data[City]);FILTER('Data';Data'[Employee]>0))

In order to check which teams have employees in only one city I tried to use the simple measure:

Total Team w/ one city = IF( [# of Cities] = 1 ; 1 ; 0 ) , but that is not aggregate-able.

Any ideas on how to do it? I'd prefer to have it as a measure instead of new calculated column so I can slice the results according to other columns in the dataset.

Thanks in advance!

@v-juanli-msft  Hello, I found this example today and it is similar to the problem that i need to solve. How would i need to adjust the formula in above example if i need to calculate the number of teams associated with Berlin only. The result should be 1. I do understand the logic but fail to write it into a formula. It is a distinct count of teams, but combined with a check within a team that city is "Berlin" and nothing else. Thank you for your help.

Hi @rrwprioste

Try these measures

# of Cities = IF(MAX([Employee])>0,CALCULATE(DISTINCTCOUNT(Data[City]),FILTER(ALL(Data),[Employee]>0&&[Team]=SELECTEDVALUE(Data[Team]))))

which Team w/ one city = IF( [# of Cities] = 1,1,0)

how many teams have only one city = 
SUMX(ALL(Data),[which Team w/ one city])

Best Regards
