Previous year measures strategy

Create a Calculation Group: In Tabular Editor, create a new calculation group. Add a calculation item for “Previous Year” using the SAMEPERIODLASTYEAR function

Define Calculation Items: You can use the following DAX code for the "Previous Year" calculation item: CALCULATE(SELECTEDMEASURE(), SAMEPERIODLASTYEAR('Date'[Date]))
Apply Calculation Group:  Once the calculation group is created, you can apply it to your existing measures in your report. This way, you don’t need to create separate measures for each previous year comparison.
