Date dimension and multiple date columns in fact table
You can have multiple relationships between your Fact table and your Date Dimension table.
So a FACT table with [Order Date] , [Ship Date] and [Delivery Date] can all be related to your Date dimension.
Only one relationship can be Active! You should set this to be the most common link.
Then you create measures per date action and use the DAX function called USERELATIONSHIP

So a measure counting the number of deliveries will specify that the Inactive relationship is to be used for that particular calculation.
A bit of a pain but it's not as bad as it sounds.
Otherwise use an MDX cube and you will have no such issues :)

Being able to define multiple date relationships from the fact table to a date dimension is critical, and more times that not you have to use 2 or 3 dates at the same time so as I understand the proposed solution that will not work. How can PowerBI say it supports a Star model and not support the basics. Another example is the fact table has multiple healthcare provider keys joining to one provider dimension, again using multiple at the same time has to work. I am concerned the perceived work arounds suggested don't work and creating and managing many copies of a dimension also sounds terrible. I hope Microsoft has an enhancement plan. Thoughts?
