AcceptorCancellationRequestV11

caaa.005.001.11

The AcceptorCancellationRequest message is sent by an acceptor (or its agent) to the acquirer (or its agent), to request the cancellation of a successfully completed transaction. Cancellation should only occur before the transaction has been cleared.

Message Construction

Every ISO20022 message has at the highest level what we call ‘building blocks’. Because the message is constructed as immutable records, the association is by composition. Below you can see the relationship between the message and its constituent building blocks: For comparison, see the ISO20022 official specification

Extensibility and generalization considerations

To facilitate generalized design patterns in the system, the AcceptorCancellationRequestV11 implementation follows a specific implementaiton pattern. First of all, AcceptorCancellationRequestV11 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, AcceptorCancellationRequestV11Document implements IOuterDocument. Because AcceptorCancellationRequestV11 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type AcceptorCancellationRequestV11.

classDiagram
    class IOuterRecord
    AcceptorCancellationRequestV11 --|> IOuterRecord : Implements
    AcceptorCancellationRequestV11Document --|> IOuterDocument~AcceptorCancellationRequestV11~ : Implements
    class IOuterDocument~AcceptorCancellationRequestV11~ {
        AcceptorCancellationRequestV11 Message
     }

Document wrapper for serialization

The only real purpose AcceptorCancellationRequestV11Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:caaa.005.001.11’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using AcceptorCancellationRequestV11.ToDocument() method. The returned AcceptorCancellationRequestV11Document value will serialize correctly according to ISO 20022 standards.

Sample of message format

This is an abbreviated version of what the message should look like.
