I created a working date table, but after creating the relationships to the 3 different tables, the date slicer is no longer showing values.
What did I do??
You use the Year field and MonthName field in Date table to create the Date slicer, right? If so, I am not able to reproduce your issue. Could you please share sample data of your three tables?
In addition, have you checked my reply in your another thread? This issue could be caused by that you have different DateTime values in the original table, and not all the datetime values in your original table match the date values in your Date table.
