RedemptionBulkOrderConfirmationV03

setr.003.001.03

Scope An executing party, for example, a transfer agent, sends the RedemptionBulkOrderConfirmation message to the instructing party, for example, an investment manager or its authorised representative to confirm the details of execution for a previously received RedemptionBulkOrder message. Usage The RedemptionBulkOrderConfirmation message is used to confirm the execution of all individual orders included in a previously sent RedemptionBulkOrder message. There is usually one bulk confirmation message for one bulk order message. Each individual order confirmation specified is identified in DealReference. The reference of the original individual order is specified in OrderReference. The message identification of the RedemptionBulkOrder message in which the individual order was conveyed may also be quoted in RelatedReference, but this is not recommended. A RedemptionBulkOrder must in all cases be responded to by a RedemptionBulkOrderConfirmation and in no circumstances by a RedemptionOrderConfirmation. If the executing party needs to confirm a RedemptionOrder instruction, then the RedemptionOrderConfirmation must be used.

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 RedemptionBulkOrderConfirmationV03 implementation follows a specific implementaiton pattern. First of all, RedemptionBulkOrderConfirmationV03 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, RedemptionBulkOrderConfirmationV03Document implements IOuterDocument. Because RedemptionBulkOrderConfirmationV03 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type RedemptionBulkOrderConfirmationV03.

classDiagram
    class IOuterRecord
    RedemptionBulkOrderConfirmationV03 --|> IOuterRecord : Implements
    RedemptionBulkOrderConfirmationV03Document --|> IOuterDocument~RedemptionBulkOrderConfirmationV03~ : Implements
    class IOuterDocument~RedemptionBulkOrderConfirmationV03~ {
        RedemptionBulkOrderConfirmationV03 Message
     }
  

Document wrapper for serialization

The only real purpose RedemptionBulkOrderConfirmationV03Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:setr.003.001.03’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using RedemptionBulkOrderConfirmationV03.ToDocument() method. The returned RedemptionBulkOrderConfirmationV03Document value will serialize correctly according to ISO 20022 standards.
