Secondly, we would need to create an expression to flag all records where the transaction date of that record was within one year of the variable we created in the first step (see In First Year of Booking column below). to apply the RFV selection to, or as a transactional selection within a further frequency virtual variable to cyprus mobile number example create the required value as a variable (see Number of Bookings in First Year column).

The screenshot below shows the required steps. We start in the top left by creating an expression to work out the difference between the first booking date and the current booking date for all bookings.
