# Service Order Updated

A reservation is created or modified in MEWS.

<Note>
  In MEWS terminology, a "Service Order" is a reservation. This single event covers both new reservations and updates to existing ones.
</Note>

## Data Synced

* Reservation details (confirmation number, dates, status)
* Room assignment
* Guest information (primary guest and companions)
* Reservation notes
* Pricing (total amount, taxes)

## Effect in ABRA

When this event is received, ABRA:

* Creates or updates the reservation record
* Creates or updates guest profiles for all guests on the reservation
* Syncs room assignment details
* Imports any reservation notes (which then enter the note processing pipeline)
* Updates reservation status (Confirmed, Checked In, Checked Out, Cancelled, etc.)
