Average of Monthly Totals

[billuran]

Hello All, Have a calendar table and facts table linked by date. I have a date filter where dates are flagged as trailing 12 month and the dates are atrributed  to a monthyear column

I can visually show count(BillIDs) by month.  But what i want to show the trailing twelve month average of the monthly totals.

IN theory something like this

calculate(Avg(Jan Total+Feb Total+March Total+....), DateFilter="TTM")

Thanks for your help.

You can try an expression like this using your existing measure in place of [Your Measure].  If no measure, wrap the expression inside CALCULATE( ) and replace [Your Measure].

Twelve Month Avg =
CALCULATE (
AVERAGEX ( VALUES ( 'Calendar'[MonthYear] ), [Your Measure] ),
ALL ( 'Calendar' ),
'Calendar'[DateFilter] = "TTM"
)

If this works for you, please mark it as the solution.  Kudos are appreciated too.  Please let me know if not.

Regards,

Pat

I guess i am confused on the VALUES ( 'Calendar'[MonthYear] )

I ahve 1 table called calendar with the MOnth year in it

I have another table called placements where I will do a measure called "total placements"=count(billid)

What do I put in the DAX again?
