Was there a change to filter flow in DAX?

[jdbuchanan71]

Did I miss a note in one of the recent updates to PowerBI?  In my example model I have Customers and Stores sitting over Orders and Quotes.

I would have bet money that pulling Store Number and Customer Number into a matrix would have resulted in either a cartesian join or an error of "Unable to determine relationship" but instead it works fine and only stores related to the customer are shown.

Keep in mind I have no measure in the visual, just customer number and store number from the two dimension tables.

But to me that means the filtering is flowing "uphill".  Down from Stores to Orders and Quotes then back up to Customers.

What am I missing?  I have attached my testing file for people to look at.

Hi

There is relationship between three tables, so I think they could affect each other when no measure. If you apply measure on it , it might will be wrong when you use single direction. You could refer to What is the Direction of Relationship in Power BI? foe details.
