DAX count unique values after union

Hi everybody,

I am trying to create measure counting unique values of particular column, which is the result of UNION of two columns with similar data from two diffrent tables. It looks much easier with example Smiley Happy

It is not my buisness caase, but similar to it.  My tables have different structure, so I can perform UNION only over columns. And the issues is that DISTINCOUNT works only with column, and in my case I can specify particular column name after UNION statement.

Please help me with this case.

Thank you in advance!

Re: DAX count unique values after union

Hi @Egor_Paulig_RUS ,

 

You can create new measure.

 

Measure = var t=DISTINCT(UNION(SELECTCOLUMNS(Table1,"column1",Table1[sales_manager]),SELECTCOLUMNS(Table2,"column1",Table2[manager])))

return COUNTX(t,[column1])

Hi @v-xicai ,

Thank you for the reply! 

Unfortunately DISTINCT doesn't want to accept table expression after UNION statement...

Re: DAX count unique values after union

Maybe something like this:

Manager # =
VAR ManagerTable1 =
    DISTINCT ( Table1[sales_manager] )
VAR ManagerTable2 =
    DISTINCT ( Table2[manager] )
VAR CombinedManagers =
    UNION ( ManagerTable1, ManagerTable2 )
VAR UniqueManagers =
    DISTINCT ( CombinedManagers )
RETURN
    COUNTROWS ( UniqueManagers )
