Set future reminders/notifications based on expiration date

[Peter_S1]

Hi,

I would like to send out a notification with a 30 day lead time from an expiration date, for example.
I’ve set up a report for daily frequency but having trouble defining the condition to evaluate the expiration date column and see it’s within 30 days of expiration. I would like the notifications to be sent out even if today’s date is past expiration date.
