Cancel a complete PNR - sabre

Question

I'm writing a service which automtically cancels a PNR left on a certain queue. This sounds pretty straight forward with the OTA_CancelLLSRQ request, however it appears I have to loop through each segment individually, or is there a way I can cancell ALL segments at once?
In the application we defined a PNR class, this class contains all of the information we can obtain with the "" call.
To cancel the PNR I currently use the following code:
MessageHeader msgHeader = new MessageHeader
{
ConversationId = "TestSession",
CPAId = licenseId,
Action = "OTA_CancelLLSRQ",
Service = new Service { Value = "OTA_CancelLLSRQ" },
MessageData = new MessageData
{
MessageId = "xxx",
Timestamp = DateTime.UtcNow.ToString("s") + "Z"
},
From = new From()
{
PartyId = new PartyId[]
{
new PartyId { Value = "WebServiceClient"}
}
},
To = new To()
{
PartyId = new[]
{
new PartyId { Value = "WebServiceSupplier"}
}
}
};
var segmentList = new List<OTA_CancelRQSegment>();
foreach (var segment in pnrObject.Segments)
{
var requestSegment = new OTA_CancelRQSegment
{
Number = segment.SegmentNumber.ToString()
};
segmentList.Add(requestSegment);
}
var request = new OTA_CancelRQ()
{
Version = "2.0.0",
TimeStamp = DateTime.UtcNow,
TimeStampSpecified = true,
Segment = segmentList.ToArray()
};
OTA_CancelRS response = null;
Policy.Handle<SoapException>()
.Or<WebException>()
.WaitAndRetry(new[]
{
TimeSpan.FromSeconds(1),
TimeSpan.FromSeconds(1),
TimeSpan.FromSeconds(1),
TimeSpan.FromSeconds(1),
TimeSpan.FromSeconds(1),
TimeSpan.FromSeconds(1),
TimeSpan.FromSeconds(1),
TimeSpan.FromSeconds(1),
TimeSpan.FromSeconds(1)
})
.Execute(() =>
{
using (OTA_CancelService serviceObj = new OTA_CancelService())
{
serviceObj.MessageHeaderValue = msgHeader;
serviceObj.Security = new Security1 { BinarySecurityToken = token };
response = serviceObj.OTA_CancelRQ(request);
}
});
It compiles & builds, but I haven't gotten around testing it just yet. :-)
In the documentation I found the following request:
<OTA_CancelRQ Version="2.0.0">
<Segment Type="entire"/>
</OTA_CancelRQ>
How do I encode this using the object model the webservice expects?

Answer 1

Steps for cancelling PNR is as follows.
STEP1: SessionCreateRQ
STEP2: TravelItineraryReadRQ
STEP3: OTA_CancelRQ
STEP4: EndTransactionRQ
STEP5: SessionCloseRQ
In case of SOAP SERVICES your request XML for STEP3 (i.e OTA_CancelRQ)will be as follows.
<OTA_CancelRQ EchoToken="String" TimeStamp="2001-12-17T09:30:47-05:00" Target="Production" Version="2003A.TsabreXML1.0.1" SequenceNmbr="1" PrimaryLangID="en-us" AltLangID="en-us" xmlns="http://webservices.sabre.com/sabreXML/2003/07" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<POS>
<Source PseudoCityCode="PCC"/>
</POS>
<TPA_Extensions>
<SegmentCancel Type="Entire">
</SegmentCancel>
</TPA_Extensions>
</OTA_CancelRQ>
I hope this will make your knowledge more clear.

Answer 2

You can specify "entire" type like the below to cancel the entire Itinerary of a PNR.
<OTA_CancelRQ Version="2.0.0">
<Segment Type="entire"/>
</OTA_CancelRQ>

Answer 3

here is the request part of my code in c#, hope this help add a refrence to proxy class for OTA_CancelRQ.
OTA_CancelRQ rq = new OTA_CancelRQ();
List<OTA_CancelRQSegment> segmentCancelList = new List<OTA_CancelRQSegment>();
OTA_CancelRQSegment segmentCancel = new OTA_CancelRQSegment();
OTA_CancelRQSegmentType segmentType = new OTA_CancelRQSegmentType();
segmentType = OTA_CancelRQSegmentType.entire;
segmentCancel.Type = segmentType;
segmentCancel.TypeSpecified = true;
segmentCancelList.Add(segmentCancel);
rq.Segment = segmentCancelList.ToArray();
Thanks.

Answer 4

cancelRQ.tPA_ExtensionsField = new CancelRequest.TPA_Extensions
{
segmentCancelField = new CancelRequest.TPA_Extensions.SegmentCancel
{
typeField = "Entire"
}
};

Answer 5

call OTA_CancelLLSRQ Perform a transaction after the original booking was completed (cancel the itinerary that was booked, in this case).
