I’ve been doing more repeats over the Advanced Data Modelling course.
Its feels like to me whenever using Power BI Data Model it should always be with 1-To-Many Rel
The Many-To-Many Rel (filtering both way) i’ve never used.
Can somenoe please explain, how and when would we need to use them? Key bullet points would really help.
Not seen anything online to show examples of why we need them.
I think if we had Many-To-Many Rel it would probably ruin a lot of the business value of using Time Intelligence anyway.
