Date difference customer orders

Hi,

 

I want to calculate the number of days between today and the last time a customer made a purchase order. I have a table with the purchase order nr as key and then the customer nr and purchase date. For every customer I want to know how long it has been since his last puchase. I tried to make a measure with the datedifference function but it never gives the correct result. Does anybody knows how to do this? Smiley Happy

 

Thanks in advance!

Calculate Max Order Date Per Customer using ALLEXCEPT and then calculate Datediff with today.

 

Time Since Last Order Date =

Var LastOrderDt = CALCULATE(MAX('P6:TimeSinceLastOrder'[OrderDate]), ALLEXCEPT('P6:TimeSinceLastOrder','P6:TimeSinceLastOrder'[CustomerId]))

Var TimeSinceLastOrderDt = DATEDIFF(LastOrderDt,TODAY(),DAY)

RETURN TimeSinceLastOrderDt

Re: Date difference customer orders

Create this measure:

 

Days Since Last Order = DATEDIFF(MAX(Sales[OrderDate]), TODAY(), DAY)

Then use it in a table with the customer key or name

This does not seems to work if I try to adjust the current date
