Scope The AcceptorCancellationAdvice message is sent by a card acceptor to notify the cancellation of a successfully completed card payment transaction. The message can be sent directly to the acquirer or through an agent. Usage The AcceptorCancellationAdvice message is sent by the card acceptor to an acquirer when the acquirer did not receive a correct response to the AcceptorCompletionAdvice message.
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

Now, we will zero-in one-by-one on each of these building blocks.

Extensibility and generalization considerations
To facilitate generalized design patterns in the system, the AcceptorCancellationAdviceV01 implementation follows a specific implementaiton pattern. First of all, AcceptorCancellationAdviceV01 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, AcceptorCancellationAdviceV01Document implements IOuterDocument. Because AcceptorCancellationAdviceV01 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type AcceptorCancellationAdviceV01.
classDiagram class IOuterRecord AcceptorCancellationAdviceV01 --|> IOuterRecord : Implements AcceptorCancellationAdviceV01Document --|> IOuterDocument~AcceptorCancellationAdviceV01~ : Implements class IOuterDocument~AcceptorCancellationAdviceV01~ { AcceptorCancellationAdviceV01 Message }
Document wrapper for serialization
The only real purpose AcceptorCancellationAdviceV01Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:caaa.007.001.01’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using AcceptorCancellationAdviceV01.ToDocument() method. The returned AcceptorCancellationAdviceV01Document value will serialize correctly according to ISO 20022 standards.
