Just getting started - and stuck already :)
Hi everybody,
I am just getting started with PowerBI, and stuck already :). Here is my question:
I have 2 tables.
Table A holds unique IDs:
1
2
3
4
Table B holds the same IDs and Country Names:
1 Belgium
2 Belgium
2 France
2 China
3 France
4 France
4 Belgium
What I would like to do is add a column to Table A providing a sum of the number of distinct countries in which the ID is available. In other words, Table A should become:
1 1
2 3
3 2
4 1
Any ideas on how I can best achieve this?
Thanks so much!
Mark

Hi
Create a relationship between table a and table b on ID's then create a DAX measure
CountryCount = (COUNTROWS(Table2))
Kind Regards
