You'll need a parameter to do this.

• [Month selector] : String parameter type. Create the values as 1, 2, 3, 4, ..., 12 and change the display text to January, February, etc.

• [YTD up to that month] :

  DATEADD('month',1,DATEPARSE('yyyy-M',DATENAME('year',TODAY()) + "-" + [Month Selector]))

DATEPARSE: The parameter value is used to generate a date representing the first of that month. For example, January would be January 1, 2016. DATEADD: This offsets it by a month, allowing you to compare against the end of the month, not the beginning.

• [PYTD up to that month]

Same as previous calculation, but replace

DATENAME('year',TODAY())   

with

STR(DATEPART('year',TODAY())-1)

Offsets the year by one.

• [YTD Sales] - Calculate year to date.

  IF [Date] < [YTD up to that month] AND DATEDIFF('year',[Date],[YTD up to that month])= 0 THEN [Measure1] END

• [PYTD Sales] - Duplicate the previous calculation and change references of YTD to PYTD.

  IF [Date] < [PYTD up to that month] AND DATEDIFF('year',[Date],[PYTD up to that month])= 0 THEN [Measure1] END

• [YTD/PYTD filter]

  MONTH([Date]) <= INT([Month Selector])
