The AcceptorCompletionAdvice message is sent by an acceptor (or its agent) to notify the acquirer (or its agent) of the outcome of the payment at the acceptor, and to transfer the financial data of the transaction to the acquirer (capture). A AcceptorCompletionAdvice message is also sent to reverse an approved authorisation and any associated financial transfer (capture), if the card payment transaction could not be completed successfully.
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 AcceptorCompletionAdviceV03 implementation follows a specific implementaiton pattern. First of all, AcceptorCompletionAdviceV03 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, AcceptorCompletionAdviceV03Document implements IOuterDocument. Because AcceptorCompletionAdviceV03 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type AcceptorCompletionAdviceV03.

AcceptorCompletionAdviceV03Document --|> IOuterDocument~AcceptorCompletionAdviceV03~ : Implements
class IOuterDocument~AcceptorCompletionAdviceV03~ {
AcceptorCompletionAdviceV03 Message
}
Document wrapper for serialization
The only real purpose AcceptorCompletionAdviceV03Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:caaa.003.001.03’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using AcceptorCompletionAdviceV03.ToDocument() method. The returned AcceptorCompletionAdviceV03Document value will serialize correctly according to ISO 20022 standards.
