Hi all,
I'm having trouble understanding why the following happens (and how to prevent it):
I have two tables, which I join via a 1:1 relation on a key.
th
The result after joining is as expected:
Now, when we add a measure: Ones = 1 and add this to the table we get a cartesian product of all project names, and a 1 on each row. Does anyone understand why this happens?
Thanks!

When you add columns from multiple tables to a visual, Power Bi creates a crossjoin of these columns producing all possible combinations but hideing the non-existing combinations. By returning a constat as a value you are forcing it to show all the combinations even if they don't exist.
Hey Tamerj1,
Thanks for replying!
If that's the case, how would I then prevent this from happening? Is there any way to detect that it's a non-existing combination (or is there a Power BI setting that let's me always hide non-existing combinations?)

You can use
IF ( NOT ISEMPTY ( TableName ), 1 )
Can I ask a follow-up question about your solution, please?
What is TableName?
