I got a DE with my users in, and a data relationshop to a survey DE with answers from the user. Each user can answer the survey multiple times, and therefor be in the survey DE many time.
Now i want to send a mail with the newest answers data in. If i just a normale Loopup() i will get the first row that matches the user. But it need to get the row with the newest Timestamp on.
This returns the first rows that matches the email for the user, i need somehow to filter the rows, and return the newest (according to the Timestamp)
