October 28 & 29: Experts share their secrets on how to pass the Fabric Analytics Engineer certification exam—live. Learn more
Hi,
I have a normal star schema in my model but there are two related dimensions that i am unsure about (see below for picture).
I am only able to connect the ID from "no of products table" to the main Fact table. That is fine but it would mean that i need to create a relationship between these two and that would break my clean star schema--one arm of the star would have an "extended dimension". Question is... is this best practice? what would you do alternatively?
I know i can merge tables but the higher granularity of the "serial number of products" table will force me to make a many to many relationship which i do not want.

Hi
To me it seems logical to join those tables.
You can follow other types of models in Power BI and still be following the best practices. It all depends on the analysis you want to make.
If you want, you can share your model and the relationships and we can try to help.
