Where do I find it?
Prices > Discounts > Flyer/Calculated/Manual > Dates tab
What does it mean?
The prebooking option is used to make a discount valid just for a specific period of time before the event.
For example, if you have an event at 17:00, you can create a discount just valid for 60 minutes before the event. It means that the discount just will be applied from 16:00h until 17:00h.
What should I do?
The pre-booking option must be activated in the 'Dates' tab when creating a discount (manual, flyer, or calculated discount). However, in this instance, you must enter the minutes before or after the event, depending on the period you wish the discount to be valid for.
In this case, if you want the discount valid from 16:00 until 17:00 for an event at 17:00, the "Relative Prebooking start/end" would be from 0 minutes to 60 minutes before the event.
