Fundamental Data Model Relationship Question

[Anonymous]

Hello,

I've created a data model with a Fact table and Dim table. I've also create a relationship(1:M) from the Dim to the Fact table. Now, when a start creating a Table Visual for my "spot-checking" needs and bring in the Key fields from both tables that I created my relationship based on, the amount of records are inflated. I would think I would only see records in the Table Visual where the Key fields match between the Fact table and Dim table but it seems as if a cross-join of some sort is happening behind the scenes but I think I'm missing something fundamental here in my understanding.

As you can see the screenshot, the 2nd Key field(From Dim table) is being replicated when the 1st Key field(From Fact table) in the screenshot is unique as I build out my Table Visual. I'm expecting to see only records where the two Key fields match. However, it seems like all records from the Dim Table will "cross join" to each record in the Fact table based on the relationship created between the tables. The Key field from the Dim table is unique and I created a 1:M relationship to the Fact table.

Any explanation would be helpful.
