Best practice for models using "between" relationships
What is the best practice for compensating for Power BI's lack of a "between" style relationship?
I'm working with tables in source systems that are intended to be joined based on a value in the fact table falling between two values in the dimension table. As designed, these tables are supposed be related by "Fact_Table JOIN Dimension_Table on Fact_Table.Date between Dimension_Table.Valid_From and Dimension_Table.Valid_To"
Other than joining these to create one table in Power Query, what is the best practice for creating a relationship like this in the data model?

If you found this post helpful, please give Kudos CThanks, pratyashasamal. Unfortunately those don't really cover my question. They do a great job covering best practices of data modelling within the kind of relationships that Power BI was designed to accomodate. Unfortunately, Power BI wasn't designed to accomodate these range-based relationships, so this exiosting documentation doesn't address how to immitate that behavior.
