Thanks for reaching out to us.

First, you need to find the dates you want to compare from the two tables, and then use the datediff function.

for example,

measure=

var _date1= minx(filter(table1,table1[column1]="xxx"), [Salesdate])

var _date2= minx(filter(table2,table2[column1]="xxx"), [Orderdate])

return datediff(_date1,_date2,day)

@refint650 , You need a common dimension joined to both tables

Sumx(Values(Order[Order]) , datediff( Min(sales[salesdate], max(Order[orderdate], days) )

same as this one
