DTCCCANOEligibleBalanceSD1V01

supl.007.001.01

The DTCCCANOEligibleBalanceSD1 message extends ISO corporate action notification (Eligible Balance market practice) message with DTCC corporate action eligible balance 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
%% DTCCCANOEligibleBalanceSD1V01 recursion level 0 with max 0
DTCCCANOEligibleBalanceSD1V01 *-- "0..1" AccountBalanceExtensionSD1 : AccountBalance
  

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

AccountBalance building block

Extension block for the information to be extended as account balance. Provides additional information regarding account balance. Contains transaction details of the stock loans, repurchase agreements (REPOs) and undelivered trades (FAILs). For comparison, see the ISO20022 official specification

Extensibility and generalization considerations

To facilitate generalized design patterns in the system, the DTCCCANOEligibleBalanceSD1V01 implementation follows a specific implementaiton pattern. First of all, DTCCCANOEligibleBalanceSD1V01 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, DTCCCANOEligibleBalanceSD1V01Document implements IOuterDocument. Because DTCCCANOEligibleBalanceSD1V01 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type DTCCCANOEligibleBalanceSD1V01.

    DTCCCANOEligibleBalanceSD1V01 --|> IOuterRecord : Implements
    DTCCCANOEligibleBalanceSD1V01Document --|> IOuterDocument~DTCCCANOEligibleBalanceSD1V01~ : Implements
    class IOuterDocument~DTCCCANOEligibleBalanceSD1V01~ {
        DTCCCANOEligibleBalanceSD1V01 Message
     }
  

Document wrapper for serialization

The only real purpose DTCCCANOEligibleBalanceSD1V01Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:supl.007.001.01’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using DTCCCANOEligibleBalanceSD1V01.ToDocument() method. The returned DTCCCANOEligibleBalanceSD1V01Document 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.

        <AcctBal>
            <!-- AccountBalance inner content -->
