How do I use the DAX function ParallelPeriod

0 votes

I have created a bog simple PowerPivot SQL Server 2008+ source query and named it Source. The query generates 168 rows: 6 IDs (100-600) and 28 dates (first of a month from Jan 2010 to Apr 2012) all cross applied together.

MeasurePriorPeriodValue := CALCULATE(SUM(Source[value]), PARALLELPERIOD(Source[eventDate]
