I apologize that I can't share the actual pbix file - I'll do my best to describe the problem.
I created a calendar table with a relationship to a CreatedOn . Both are in a common 'Date' format - i.e. 1/1/2017.
However, time intelligence functions do not work at all. I want to see the count of records with date YTD, and I have the following expressoin:
Custom Col = CALCULATE ( COUNTA(NameOfSomething), DATESYTD('Calendar'[Date]) )
Yet I am seeing ALL records. I get the exact same results with no DATESYTD filter applied at all.
Any common reasons why this might occur? I can provide more details if necessary. Thanks again!
