LTM compared side by side and YOY comparasion

[MrNoob]

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.

Hi @MrNoob,

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.

Best Regards,

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]))
