Car history
A car history display is a view of the entries made to make or amend a booking and the responses received from car suppliers. It is sometimes necessary to view the history of a car transaction. This can be done before or after the customer has traveled. Past date booking retrieval may be needed for a booking that is past dated.
The entry to view history is *H.
History is often more than one screen length. Enter MD to move down and MU to move up. The first two lines of history are part of the original transaction and remain at the top of all historical data.
Historical data is cumulative and is always added at the top of the displayed history. To see information from its creation to its current state, start at the bottom and work up.
When a booking file is created or amended, and the booking file is end transacted, a CRDT time stamp is added with a RCVD- source above it. The RCVD line automatically adds the details of the sign-on in use at the time. Each subsequent entry made in that transaction is shown above these lines.
The following is a history example from a Travelport+ agency booking file. The user entered the received from R.EW in this example, and the system stamped the sign-on (blurred out in this example)
The actions within each CRDT transaction timestamp can be read left to right. They are preceded at the left-hand side with a history code indicating the action.
For example, AS for add segment or XS – for cancel segment.
Recognizing these codes takes practice. Please refer to H/HIST to view the history codes. Below is the first screen of history codes:
If you are viewing a booking file with air and/or hotel segments too, you can look at only car itinerary history using the entry *HIC.
Enter: *HIC
To recap: read each CRDT line as the time and date of the transaction and all the entries above each CRDT apply to that date and time.
Common car history action codes to look for are:
-
XS – canceled segment.
-
AS – added new segment.
-
AES – added estimated total data.
-
XES – deleted estimated total data.
