AmendmentV01

cain.020.001.01

The Amendment message can be initiated by any party and received by any party (acquirer, agent or issuer).

This message is used to inform the originator that the original message has been corrected/amended and then forwarded to the destination on behalf of the originator. It contains a copy of the original message and any errors found. It may also contain any corrections and/or amendments that were made to the original 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

Extensibility and generalization considerations

To facilitate generalized design patterns in the system, the AmendmentV01 implementation follows a specific implementaiton pattern. First of all, AmendmentV01 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, AmendmentV01Document implements IOuterDocument. Because AmendmentV01 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type AmendmentV01.

classDiagram
    class IOuterRecord
    AmendmentV01 --|> IOuterRecord : Implements
    AmendmentV01Document --|> IOuterDocument~AmendmentV01~ : Implements
    class IOuterDocument~AmendmentV01~ {
        AmendmentV01 Message
     }
  

Document wrapper for serialization

The only real purpose AmendmentV01Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:cain.020.001.01’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using AmendmentV01.ToDocument() method. The returned AmendmentV01Document 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.

<Document xmlns="urn:iso:std:iso:20022:tech:xsd:cain.020.001.01">

        <Hdr>
            <!-- Header inner content -->

        <SctyTrlr>
            <!-- SecurityTrailer inner content -->
