Hi everyone.
I need help with a calculation with a Trend.
The excel formula that we use is mannualy changed each month, but we want to have it in Power Bi without of course de mannualy calculations.
Trend = Average( of the last 3 months)
Example, if we are in April the Trend should be the Average of the values from Jan, Feb and Mar, and if we are in May should be from Feb, Mar, Apr.
I have a Calendar table with the following structure.
Thank you in advance
@Anonymous , try a measure like given below with Date Table
Rolling 3 = divide( CALCULATE(sum(Sales[Sales]),DATESINPERIOD('Date'[Date ],eomonth(MAX('Date'[Date]),-1),-3,MONTH)) ,
CALCULATE(distinctCOUNT('Date'[Month Year]),DATESINPERIOD('Date'[Date],eomonth(MAX('Date'[Date]),-1),-3,MONTH), filter(Sales,not(isblank((Sales[Sales]))))))
Or
Rolling 3 = CALCULATE(Average(Sales[Sales Amount]),DATESINPERIOD('Date'[Date ],eomonth(MAX('Date'[Date ]),-1),-3,MONTH))
