ReversalInitiationV02

cain.005.001.02

The ReversalInitiation message is sent by an acquirer, an originator or an agent to an issuer to request or advise of the reversal of an authorisation by the issuer. A reversal is a partial or complete nullification of the effects of a previous authorisation, financial presentment or financial accumulation presentment that cannot be processed as instructed (for example, is undeliverable and cancelled or the acquirer timed out waiting for a response).

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 ReversalInitiationV02 implementation follows a specific implementaiton pattern. First of all, ReversalInitiationV02 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, ReversalInitiationV02Document implements IOuterDocument. Because ReversalInitiationV02 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type ReversalInitiationV02.

classDiagram
    class IOuterRecord
    ReversalInitiationV02 --|> IOuterRecord : Implements
    ReversalInitiationV02Document --|> IOuterDocument~ReversalInitiationV02~ : Implements
    class IOuterDocument~ReversalInitiationV02~ {
        ReversalInitiationV02 Message
     }
  

Document wrapper for serialization

The only real purpose ReversalInitiationV02Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:cain.005.001.02’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using ReversalInitiationV02.ToDocument() method. The returned ReversalInitiationV02Document value will serialize correctly according to ISO 20022 standards.
