How to remove duplicate from measure

[vjnvinod]

hi Team,

I am using a function countrows to get the count details of the regions, however i  don't want the duplicate to be counted 2 or 3 times based on their repetition

for instance if Canada is repeating 3 times, it should only count as 1 

how do i remove the duplicate?

can someone help me with the measure?

Hi, @vjnvinod 

Based on your description, I created data to reproduc your scenario. The pbix file is attached in the end.

MSL:

You may create a measure as below.

Count = 
COUNTROWS(
    DISTINCT(MSL[Region])
)

Result:

@vjnvinod - Use DISTINCTCOUNT or maybe COUNTROWS(DISTINCT(...))

HI @vjnvinod ,

Use DISTINCTCOUNT to count unique rows for a column rather than using COUNTROWS or you can use DISTINCT with COUNTROWS.

UniqueCount = DISTINCTCOUNT(tablename[column])

OR

UniqueCount = COUNTROWS(DISTINCT(tablename[column]))

Thanks,

@vjnvinod ,
Countrows function returns count of rows per criteria.
If there are 3 rows for Canada, it will return value 3.
On the other hand, if you would like to count have many distinct items(for example) were sold in Canada, they you should write measure like this:

DistinctCount = DISTINCTCOUNT('Item'[Item Id])

Furthermore, if you are using list or matrix, it will give you unique combinations of data (unique combinations of country/region) so there should be no duplicate rows on visualization.
