I am trying to calculate the LTM and the previous periods LTM, however, i want to display them side by side. Then calculate the YOY difference, displayed for the corresponding month. I am using a Year and Month slicer. My data is upto Feb 2018. I want to display a dynamic rolling LTM line chart.
The matrix best displays my issue.
What's the formula that you used? Seems you need a function SAMEPERIODLASTYEAR. Please share a sample, then we can provide more details of the solution.
This is the code i am using in order of calculations.
SP = ((([PAX]/[Bookings IND PAX])-([Bookings APM]/'Bookings Meassures'[Bookings IND PAX])))*100 LTM SP = CALCULATE ( [SP], DATESBETWEEN ( 'DATE'[Date], NEXTDAY ( SAMEPERIODLASTYEAR ( LASTDATE ('DATE'[Date]) ) ), LASTDATE ('DATE'[Date] ) ) ) LY LTM SP = CALCULATE([LTM SP],SAMEPERIODLASTYEAR('Date'[Date]))
