Would love some help on Trending out Sales Year to Go

[Anonymous]

Hello There,

I have 2 Fact Tables

1 is Fact POS Table- Using "POS Value USD" Column

2 is Fact Shipments Table- Using "Gross Ships USD" Column

My Shipments table has actuals (year to date actualized shipped $), and it also includes a forecast for remaining year periods

I would like to be able to trend out my "POS Value USD" (See orange line in chart above) using Year to Date periods, and Last 3 Periods, to get a forecast for the "POS Value USD" for the reamining periods of the year. 

What would be the best way to achieve this? Thanks so much!

Hi

I understand you forcasting remaining year by average sales of last 3 periods

if so, please try this measure for Orange line

Orange_line =
var a = CALCULATE (YTD sales, DATEADD(date,-1,year)

var b = CALCULATE (YTD sales, DATEADD(date,-2,year)

var c = CALCULATE (YTD sales, DATEADD(date,-3,year)
return if (Date <= TODAY(), YTD sales, (a+b+c)/3)
