I have two tables. One contains data including customer number and whether they have had a fall and if so, on what dates they have had a fall. As such, it can contain multiple rows for one customer if they have had multiple falls. The other tells me if a customer has been to hospital any number of times so also has multiple rows for one customer. I want to do a look up in the first table which will tell me if a customer has been to hospital within 2 days of having a fall.
@NikkiSavage , Need sample data for that.
example
New column =
var _cnt = countx(Table2, Table2[Customer] = Table1[Customer] && Table2[Date] >= Table1[Date] && Table2[Date] <= Table1[Date] +2),Table2[Customer] ) +0
return
if(_cnt>0, True(), False())
