SSAS DAX time intelligence previous year and calculation gives wrong value
问题 We want to show current periods sales versus previous period sales. To show the previous period we make use of a date dimenion table and the following calculation: CALCULATE(SalesValueGross; DATEADD(Date[Date]; -1; YEAR)) Unfortunately somehow it shows minor (decimal) differences when comparing years. The difference get's bigger when we slice to months. Another issue we have is that this calculation does not seem to work when comparing (for example) week 1 - 2015 with week 1 - 2014. Any help
