Hi everyone , Please

I want to calcualte this KPI(measure DAX) in day - quarter-month-year

This is Formula :

Internal order processing time = Order[Order purchased date] - Order[order delivered date]

 Thank

I would create new columns for day, month, quarter and year, like

Internal order processing time ( days) =
DATEDIFF( Order[Order purchased date], Order[order delivered date], DAY)
Internal order processing time ( months) =
DATEDIFF( Order[Order purchased date], Order[order delivered date], MONTH)

You could then create measure to show average time, min / max etc.
