A FraudDispositionInitiation message is usually sent by an agent to a financial institution acting as an acquirer or as an issuer to report about the disposition of a confirmed fraudulent transaction.
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.
Header building block

Extensibility and generalization considerations
To facilitate generalized design patterns in the system, the FraudDispositionInitiationV02 implementation follows a specific implementaiton pattern. First of all, FraudDispositionInitiationV02 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, FraudDispositionInitiationV02Document implements IOuterDocument. Because FraudDispositionInitiationV02 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type FraudDispositionInitiationV02.
classDiagram class IOuterRecord FraudDispositionInitiationV02 --|> IOuterRecord : Implements FraudDispositionInitiationV02Document --|> IOuterDocument~FraudDispositionInitiationV02~ : Implements class IOuterDocument~FraudDispositionInitiationV02~ { FraudDispositionInitiationV02 Message }
Document wrapper for serialization
The only real purpose FraudDispositionInitiationV02Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:cafr.003.001.02’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using FraudDispositionInitiationV02.ToDocument() method. The returned FraudDispositionInitiationV02Document value will serialize correctly according to ISO 20022 standards.
