AccountHoldingInformationV05

sese.018.001.05

Scope An executing party, for example, a (old) plan manager (Transferor), sends the AccountHoldingInformation message to the instructing party, for example, a (new) plan manager (Transferee), to provide information about financial instruments held on behalf of a client. Usage The AccountHoldingInformation message is used to provide information about one or more ISA or portfolio products held in a client’s account.

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

BusinessFlowDirectionType building block

Identifies the business flow direction type (assets to be delivered or received). Identifies the business flow, in order to determine the role of the parties in the business process. This indicator is very important when there are multiple intermediaries in the exchange of information process. For comparison, see the ISO20022 official specification This message is declared as BusinessFlowDirectionType1Code in the ISO specification. In our implementation, it is represented in source code as BusinessFlowDirectionType1Code. Due to global using directives, it is treated as a System.String by the compiler and runtime.

PrimaryIndividualInvestor building block

Information identifying the primary individual investor, for example, name, address, social security number and date of birth. Human entity, as distinguished from a corporate entity (which is sometimes referred to as an ‘artificial person’). For comparison, see the ISO20022 official specification

Extensibility and generalization considerations

To facilitate generalized design patterns in the system, the AccountHoldingInformationV05 implementation follows a specific implementaiton pattern. First of all, AccountHoldingInformationV05 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, AccountHoldingInformationV05Document implements IOuterDocument. Because AccountHoldingInformationV05 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type AccountHoldingInformationV05.

classDiagram
    class IOuterRecord
    AccountHoldingInformationV05 --|> IOuterRecord : Implements
    AccountHoldingInformationV05Document --|> IOuterDocument~AccountHoldingInformationV05~ : Implements
    class IOuterDocument~AccountHoldingInformationV05~ {
        AccountHoldingInformationV05 Message
     }
  

Document wrapper for serialization

The only real purpose AccountHoldingInformationV05Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:sese.018.001.05’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using AccountHoldingInformationV05.ToDocument() method. The returned AccountHoldingInformationV05Document value will serialize correctly according to ISO 20022 standards.
