DTCCCACSSD1V01

supl.033.001.01

The DTCCCACSSD1 message extends ISO corporate action Instruction Cancellation Request Status Advice (CACS) message with DTCC corporate action elements not covered in the standard 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

     direction LR
%% DTCCCACSSD1V01 recursion level 0 with max 0
DTCCCACSSD1V01 *-- "0..12" ReorganisationInstructionDetailsSD4 : ReorganisationInstructionCancellationDetails
  

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

ReorganisationInstructionCancellationDetails building block

Supplementary data extending corporate action instruction cancellation request status advice message with corporate action reorganisation elements not covered in the standard message. Provides additional information regarding corporate action reorganisation instruction details. For comparison, see the ISO20022 official specification

Extensibility and generalization considerations

To facilitate generalized design patterns in the system, the DTCCCACSSD1V01 implementation follows a specific implementaiton pattern. First of all, DTCCCACSSD1V01 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, DTCCCACSSD1V01Document implements IOuterDocument. Because DTCCCACSSD1V01 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type DTCCCACSSD1V01.

    class IOuterRecord
    DTCCCACSSD1V01 --|> IOuterRecord : Implements
    DTCCCACSSD1V01Document --|> IOuterDocument~DTCCCACSSD1V01~ : Implements
    class IOuterDocument~DTCCCACSSD1V01~ {
        DTCCCACSSD1V01 Message
     }
  

Document wrapper for serialization

The only real purpose DTCCCACSSD1V01Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:supl.033.001.01’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using DTCCCACSSD1V01.ToDocument() method. The returned DTCCCACSSD1V01Document 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:supl.033.001.01">
    <DTCCCACSSD1>
        <ReorgInstrCxlDtls>
            <!-- ReorganisationInstructionCancellationDetails inner content -->
        </ReorgInstrCxlDtls>
    </DTCCCACSSD1>
</Document>
