Forming relationships with different data

Many to many is supported but it should not create two patch for the same set of table.

In case you have dates. It is always preferred to use date calendar.

You can also create a month calendar

MonthTable = 
    var FullCalendar = ADDCOLUMNS(CALENDAR("2016/1/1","2017/12/31"),"Month Number",MONTH([Date]),"Year",YEAR([Date]),"Year-Month",LEFT(FORMAT([Date],"yyyyMMdd"),6),"Month Name",FORMAT(MONTH([Date]),"MMM"),"Year-MonthName",YEAR([Date]) & " " & FORMAT(MONTH([Date]),"MMM"))
    return 
    SUMMARIZE(FullCalendar,[Month Number],[Year],[Year-Month],[Year-MonthName])

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.
