DTCCCACNSD1V10

supl.006.001.10

The DTCCCACNSD1 message extends ISO corporate action cancellation advice (CACN) 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

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

Pagination building block

Page number of the message and continuation indicator to indicate that the multi-parts message is to continue or that the message is the last page of the multi-parts message. Number used to sequence pages when it is not possible for data to be conveyed in a single message and the data has to be split across several pages (messages). For comparison, see the ISO20022 official specification

}

Pagination1 members

PageNumber Page number. IsoMax5NumericText - Required 1..1
LastPageIndicator Indicates the last page. IsoYesNoIndicator - Required 1..1

Notification building block

Notification information to be extended as supplementary data to cancellation advice. Customer security identification reference information.

SecurityOfInterestMatchingSecurity Security identifier that is used to match the customer’s SOI (Security of Interest) to the GCA VS Security Cross Reference. SecurityIdentification20 - Optional 0..1

GeneralInformation building block

Information to be extended as supplementary data to general information. Provides additional information regarding corporate action general information details. For comparison, see the ISO20022 official specification

CorporateActionGeneralInformationSD40 members

Member name Description Data Type / Multiplicity
PlaceAndName Xpath to the element that is being extended. IsoMax350Text - Optional 0..1
EventType DTCC (The Depository Trust and Clearing Corporation) native corporate action event type name. Used in place for the events that cannot be classified by ISO Code and are marked as OTHR. Can be used in combination with DTCC sub event type (when provided) to identify the event. For an example: a distribution based on recapitalisation event will be presented as event type: OTHR in standard message. DTCC native event type would be Distribution (DIST) and DTCC sub event type would be Recapitalisation. ExtendedEventType6Code - Optional 0..1
SubEventType DTCC (The Depository Trust and Clearing Corporation) corporate action sub event type name further defines the event type. For an example: a cash dividend event eligible for dividend reinvestment at DTC election will be noted as event type: cash dividend (DVCA) and DTCC sub event type: DRIP( DTC only). DTCCSubEventType8Code - Optional 0..1
EventGroup DTC processing domain/ category for event types. EventGroup4Code - Optional 0..1

UnderlyingSecurity building block

Information to be extended as supplementary data to underlying security details. Provides additional information regarding underlying security details. For comparison, see the ISO20022 official specification

Extensibility and generalization considerations

To facilitate generalized design patterns in the system, the DTCCCACNSD1V10 implementation follows a specific implementaiton pattern. First of all, DTCCCACNSD1V10 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, DTCCCACNSD1V10Document implements IOuterDocument. Because DTCCCACNSD1V10 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type DTCCCACNSD1V10.

classDiagram
    class IOuterRecord
    DTCCCACNSD1V10 --|> IOuterRecord : Implements
    DTCCCACNSD1V10Document --|> IOuterDocument~DTCCCACNSD1V10~ : Implements
    class IOuterDocument~DTCCCACNSD1V10~ {
        DTCCCACNSD1V10 Message
     }

Document wrapper for serialization

The only real purpose DTCCCACNSD1V10Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:supl.006.001.10’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using DTCCCACNSD1V10.ToDocument() method. The returned DTCCCACNSD1V10Document value will serialize correctly according to ISO 20022 standards.
