Count occurrences on a One to Many Relationship

[Anonymous]

Hi Experts

I have two tables A and B. In table A i have unique instance of the values (client names) in table b i have multiple instance of the client names and multiple instance of the True or False for the column "ABC" for each client...

I want to return the count of True values for each client Name.

Create a one to many relationship between the two tables on the client name then use the following measure

Measure = CALCULATE ( COUNTROWS ( TableB ), TableB[ABC] = TRUE () )

This will give the amount of True values, this is assuming the true/false values are stored as a logical. If they are stored as text then just swap out TRUE () for "True"
