Chris Webb on using parameter tables in Power BI:
And there you have it: a parameter table in PowerBI.com. To be honest, I think there are slightly too many fiddly steps for users to follow in this technique for me to be happy recommending its use unconditionally, but it should be useful in some scenarios. Hopefully there will be an easier way of accomplishing the same thing in Power BI in future…
Sounds like it’s not as easy to do as in Power Query, but Chris does provide nice step-by-step instructions.
