Trying to get employee active, with min of slicer and last buy

[JoanElGran1899]

Hi everyone,
I am here again with more doubts to solve, can anyone help me? jeje
We have a Dim Calendar with a date, related to the orders table by the date of the different purchases.
We want to know Dynimic the employees active ( that his last purchase =>365 days of the min date of the slice), it is a little bit tricky.
We made a datediff but it does not work.

selected date = seleted ddd


The aim of this metric is to know the active employees in the last 365 days of the minimum date of the slide.

Many thanks,
Joan
