I need to get a 12 month rolling average to work but I get the "Time intelligence quick measures can only be grouped or filtered by the Power BI-provided date hierarchy or primary date column." error. I have tried many suggestions on this forum but nothing has worked for me yet.
I need to get a rolling average of the count of events, either by using the Car Number field or the unique Service Event ID field.
The data look like this but with many more rows:
