Hi @parry2k,I am not opposed to using those time intelligence calculations, but the DAX expression that I have posted provides more flexibility because you can compare any period to the exact same time range over the previous period by adjusting the slicer. We should redefine the concept of previous month as previous month in the selection made outside of the matrix. Next easy step is understanding number of days between start and end of period, which is simply by using DateDiff() DAX function as below; I add them all in the report as Card Visuals (one for each measure), and here is the result so far; After finding number of days in this period, start, and end of current period, it is a simple calculation to find the previous period. It is a token of appreciation! If you filter context is at month level; then you get the same month last year. Cheers There are way too many solution available to achieve MoM/QoQ/YoY based on the slicer selection, like calculation groups or you can use Row Based time intelligence by following this blog postRow-based Time Intelligence - Phil Seamark on DAX. Today's post is about how you compare Current year and Previous year sales using DAX- SAMEPERIODLASTYEAR function in Power BI. depends on the context.
Soviet Union - Wikipedia Depends on the filter context you may get a different result from these functions.

When you create a year-over-year in DAX, you usually compare two set of dates from the calendar, regardless of the presence of data in all the days of the period. Using this model, any existing measure can compute the value in the current or comparison period with a simple change in the active relationship. The first step is to create a base measure to calculate Sales Amount: I will straight away create another measure, which will calculate same figures, but shifting one month back: There are multiple different ways to calculate this measure, but I prefer using DATEADD() function since it gives me more flexibility with shifting periods (thats an official excuse:)In reality, Im coming from the SQL world, where DATEADD() is one of the most important functions when working with dates). You would need a table that shows dates, and then a measure with the SamePeriodLastYear function as mentioned in this post. Focusing on only two points in time can skew perceptions by ignoring broader trends or using a poorly chosen baseline.
Power BI - Year over Year (YOY) Reports using SAMEPERIODLASTYEAR Once every calculation is ready , we need to test the authenticity of the calculation by creating a crosstab.This will help us to validate all the calculation which we are planning to use in this dashboard .
