Export to Excel Not Working Properly for Measure with SAMEPERIODLASTYEAR

Hi All,

Greetings!

I have a measure as below. This works fine with a calendar date slicer. However, upon exporting to excel it shows 0% in all rows. Not sure if I'm missing anything here.

Previous Year Rate = CALCULATE([This Year Rate], SAMEPERIODLASTYEAR(CalendarDate[Date]) )

Report design specs:: Line Chart with Calendar Hierarchy (Year->Qtr->Month) in Axis, [This Year Rate] and [Previous Year Rate] measure in values.

Note: Both the measures are in % format.

Any help is appreciated.

Thanks.
