Combine columns from different tables for one filter

Meeresblume , Not very clear to me. But you need a common date table. This table should join with date( not date with time) of all the tables. Now you can use this date table to filter different tables 

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :radacad sqlbi My Video Series Appreciate your Kudos.
