How to count a specific text value in a different table

[Anonymous]

Hi all!

I just started working with powerBI and can't find the right solution for my question.  I have the following tables/collumns

Table A 

- A collumn with names

Table B (customers)

- Collumn with names where customers bought something (Related to collumn in table A)

So in table A i want to add a collumn with the count of the names in collumn 1, and how many times they are mentioned in table B. I tried some count and if statements but haven't figured out the right statement.

Hi @Anonymous 

it depends on full your data model, but in common case it could be enogh to create the next measure (if you have relationships between tables) to table1

Measure = calculate(countrows('Table2'))

Hello @Anonymous ,

You can create a calculate column on the Table A:

CALCULATE(

         COUNT(Table B[name])

)

Or you can do the same with a measure. I think your column didn't work because you are not in the same context, for this you should use CALCULATE.

Thanks,

Guilherme

Can i add a last date filter here as well? So that i can count only the values from the last date available.
