How to add a placeholder Item to an Itinerary
Placeholder Items are generic Items that are marked as placeholders. They are used within Itineraries so you can add prices to services where it is unknown at the time of quoting or booking, which exact Item will be confirmed for your customer. Unlike general Items, placeholder Items can be replaced in an Itinerary even after the Itinerary has been converted to a confirmed booking.
