Count Distinct Values of column in a Calculated Table Variable in DAX Measure

Hi. I have tables a and b. In my measure, I need to create a calculated table consisting of one column from table a (let's call it "ca") and another column from table b, "cb". now, within the measure, I need to do a distinct count on values from column cb in the calculated table. 


Table b 1 ---- * Table b

Measure I tried:

var vAcctsTbl=calculatetable(  ADDCOLUMNS(values(b[cb]) ,  "AcctKey", max(a[ca]) ) )
Now, here is the problem is that dax doesn't allow me to do

Is there any way by which I can accomplish this? Please, note that I don't have the option of creating a physical table because I am working on a live connection to SSAS. Thanks.


Ok. I used worked. Thanks.

To make the question more generic, can I count the distinct values of a specific column in a calculated table variable in a dax measure? Please, note that the data source is analysis services, so the solution cannot involve creating an actual table.

Ok. I used worked. Thanks.
