Need help wirting the dax equation to to farecast based on YoY values.
I need to forecast the sales bases on same period last year ( custom fiscal calendar can't use time intellingence function) .
Let say we are in fiscal week 10 and I need to forecast all values from week 11 on.
Forecast sale :
current_week sale + average 4 YoY sales (starting week 11 last year till week 7 last year)
YoY = CY_Sale - PY_Sale
CY Sale = calculate(SUM('sales'[sales Amount]), fiscal_week <= Current_week)
PY_Sale = calculate(SUM('sale'[Sales Amounr]), 'date'[year] = prev_yr)
