How would I populate future months

[Tripb44]

 I need to apply the avg 3 month calc to feature dates as a projection.  How would I populate future months based linking the days such as the below highlighted cells for reference.

Hi @Tripb44 ,

You can calculate the rolling avg 3 month like this:

3 MO avg = 
CALCULATE(
    AVERAGEX (
        VALUES ( 'Date'[Calendar Year Month] ),
        [Sales Amount]),
    DATESINPERIOD('Date'[Date], MAX ( 'Date'[Date] ), -3, MONTH )
)

Processing of data for future months, you can read this case for reference:Solved: Rolling Average for Future Months - Microsoft Power BI Community

If the problem is still not resolved, please provide detailed error information and let me know immediately. Looking forward to your reply.

Best Regards,
Henry

@Tripb44 , A measure like this with date table

Rolling 3 = divide( CALCULATE(sum(Sales[Sales]),DATESINPERIOD('Date'[Date ],MAX('Date'[Date]),-3,MONTH)) ,
CALCULATE(distinctCOUNT('Date'[Month Year]),DATESINPERIOD('Date'[Date],MAX('Date'[Date]),-3,MONTH), filter(Sales,not(isblank((Sales[Sales]))))))

I have the rolling 3 calc.  I need to fill future dates with using the rolling 3 calc to mirror the days.
