Customers who bought and not bought some product in last 90 days

Question

And another one which shows me those whose bought products B and C in last 90 days.

(based in my filter date context)

Below is like it should be:

Can someone help me?

Here is a sample data if needed:

Answer 1

尝试以下方法：

IfBought = IF(
              COUNTROWS(
                  FILTER(FactSales,
                      RELATED('Product'[Product]) IN {"B", "C"} &&
                      RELATED('Calendar'[Date]) > TODAY() - 90)
                  ) > 0,
              1, 0)

请注意，尽管从今天起5月1日比今天早了90天，所以除非您将90更改为114或更高，否则您不会得到想要的结果。
