How to count rows that are related to another table?

Hi,

 

I have two tables and they are connected.

 

In Table A, Client ID is unique but in Table B it is not.

Now I want to count the number of rows in Table A that have client ID existed in Table B. I'd like to use "countrows" function instead of "distinctcount" for another calculation purpose. Does any one know how to do it?

 

Thanks a lot in advance!!

Hi @Ying_P,

 

You can create a measure below:

 

Measure = COUNTROWS(FILTER('Table A',CONTAINS('Table B',[Client ID],'Table A'[Client ID])))

So what should we do if we wanted to return only certain values ​​from table B? For example, what should we do if we wanted to filter client IDs with Product Category ID = 'Kids Tops'?

So simple! Thank you. I added a + 0 at the end to avoid blank when there is no match.

Thank you very much,. It works perfectly!
