As part of our transition from the old guest invoice to the new guest folio with the nightly rates breakdown, reservations with a future check-in date automatically get the new folio, while reservations with a past check-in date need to be migrated manually.
If you come across a reservation you cannot edit, you will be instructed to upgrade it.
This update will not affect any of the reservation's existing amounts or totals - it will just provide additional information such as the nightly breakdown.
