Summary

How to return Year to Date (YTD) this year vs. YTD previous years for turnover metrics.

I'm trying to return year to date turnover and compare it against how we were doing year to date in previous years.   The goal is to be able to directly compare time periods (Month) to quickly understand how we are trending.   I am able to return the last 2 years of data for example in the workforce trends subject area using this filter (xml attached) but need to return only to May (Current Date) for both time periods.  

CAST("Time"."Calendar Year" AS INT) BETWEEN (@{YEAR}{VALUEOF("CURRENT_YEAR")} - 1) AND @{YEAR}{VALUEOF("CURRENT_YEAR")}
