Standard Deviation based off of a Measure instead of Column

Hi PBI Community, 

I'm looking to plot a rolling 12 month Standard Deviation of the Complaint Rate line, which is a measure of Complaints Number divided by 3 Month Sales Average (both numerator and denominator are also measures). I'm under the impression that STDEV.S can only be applied to a column, so I'm hoping to get some help on how to work around this. A measure of a calculated column works for single selected Sub Categories but not for combinations of multiple Sub Categories, which is what this report will primarily use.




Thank you!

@tamerj1 any clues to lead us to victory?!


perhaps someone like this?

VAR CurrentMonth =
SELECTEDVALUE ( 'Date'[Month] )
ADDCOLUMNS ( ALLSELECTED ( 'Date'[Month] ), "@STD", STDEV.S ( [Measure] ) ),
'Date'[Month] = CurrentMonth

I'm trying to do something similiar and think the solution has to be somehow using summarize/summarize columns and creating a virtual table to calculate the Standarad Deviation off of.  Is that possible or has anyone done that before?
