Hi everyone
I attended the London Power BI users group recently where Alberto Ferrari was speaking about time intelligence (excellent presentation BTW!). I got the impression that he seemed quite sceptical of bi-directional relationships in a Power BI data model so I was just wondering about the reasons behind this and want to find out a bit more.
More specifically, in terms of optimisation, will my DAX code execute significantly faster in a single direction environment or are there other reasons that need to be considered?
Many thanks
Simon
