Measure for rolling 12 month average

Hi,   I`m looking for a measure to calculate average Full time equivalent (FTE) over a 12 month rolling period.  I have a table that shows the sum of FTE for each month.  What I would like is an ad...

    I see,

    Rolling12month = 
var v_dates =  DATESINPERIOD( Rolling_Calendar_Lookup[Date]; MAX( Rolling_Calendar_Lookup[Date] ); -12;  MONTH )
return
AVERAGEX(v_dates;[sum FTE])

    Power BI file here.

     

    Hope it helps. 

    Kind regards,

    Steve.

Hi,

 

See;

Rolling12month = CALCULATE(    AVERAGE( 'Table'[Sum of FTE]);    DATESINPERIOD( 'Date'[Date]; MAX( 'Date'[Date] ); -12;  MONTH ))

Power BI file is here. 

 

Some tweaking might be needed because the RT needs to be calculated on an aggregate. Pls share detailed data in case this does not work. 

 

Kind regards,

 

Steve.

Hi Steve, 

 

Thanks for the response. I have tried this but dont quite get the result.  This is probably my fault though as I think i have over-simplied the information provided.  I have set up a pbix file which mirrors the real file in terms of format of data loaded and model structure.  Can you please have another look.

 

Much appreciated.

 

Brendan

      Hi Steve, 

       

      Many thanks.  That's worked exactly as expected.

      Steve,

      Hopefully you're still active. How would I write this so that it ignores my Date slicer and continues to average back past the 1st date shown? For example, in OPs example April 2017 is average as just one month, but I would like to average the 12 months prior to April 2017.

       

      Thanks
