The SecuritiesAccountModificationRequest message is sent by an instructing party to the executing party to instruct the update of an existing securities account by amending its existing attributes or by providing additional attibutes details.
Usage: Processing and confirmation of the securities account creation request message are provided via a SecuritiesAccountStatusAdvice 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
classDiagram
direction LR
%% SecuritiesAccountModificationRequestV01 recursion level 0 with max 0
SecuritiesAccountModificationRequestV01 *-- "0..1" MessageHeader1 : MessageHeader
SecuritiesAccountModificationRequestV01 *-- "1..1" SecuritiesAccount19 : AccountIdentification
SecuritiesAccountModificationRequestV01 *-- "1..1" SecuritiesAccountModification2 : Modification
SecuritiesAccountModificationRequestV01 *-- "0..1" SupplementaryData1 : SupplementaryData
Now, we will zero-in one-by-one on each of these building blocks.
MessageHeader building block
Common business identification for the message. Set of characteristics, such as the identification or the creation date and time, specific to the message. For comparison, see the ISO20022 official specification

%% MessageHeader1 recursion level 0 with max 1

}
MessageHeader1 members
| Member name | Description | Data Type / Multiplicity |
|---|---|---|
| MessageIdentification | Point to point reference, as assigned by the sender, to unambiguously identify the message. Usage: The sender has to make sure that MessageIdentification is unique for a pre-agreed period. | IsoMax35Text - Required 1..1 |
| CreationDateTime | Date and time at which the message was created. | IsoISODateTime - Optional 0..1 |
AccountIdentification building block
Identification of the securities account to be updated in the executing party system. Account to or from which a securities entry is made. For comparison, see the ISO20022 official specification

SecuritiesAccount19 members
| Member name | Description | Data Type / Multiplicity |
|---|---|---|
| Identification | Unambiguous identification for the account between the account owner and the account servicer. | IsoMax35Text - Required 1..1 |
| Type | Specifies the type of securities account. | GenericIdentification30 - Optional 0..1 |
| Name | Description of the account. | IsoMax70Text - Optional 0..1 |
Modification building block
Further details about the requested modification. Specifies the details of the modification to be applied on the securities account reference data. For comparison, see the ISO20022 official specification

class SecuritiesAccountModification2{

SecuritiesAccountModification2 members
| Member name | Description | Data Type / Multiplicity |
|---|---|---|
| ScopeIndication | Specifies the type of requested modification. | DataModification1Code - Required 1..1 |
| RequestedModification | Specifies which elements to be modified for the securities account reference data. | ISecuritiesAccountModification2Choice - Required 1..1 |
SupplementaryData building block
Additional information that cannot be captured in the structured elements and/or any other specific block. Additional information that can not be captured in the structured fields and/or any other specific block. For comparison, see the ISO20022 official specification

SupplementaryData1 members
| Member name | Description | Data Type / Multiplicity |
|---|---|---|
| PlaceAndName | Unambiguous reference to the location where the supplementary data must be inserted in the message instance. In the case of XML, this is expressed by a valid XPath. | IsoMax350Text - Optional 0..1 |
| Envelope | Technical element wrapping the supplementary data. | IsoSupplementaryDataEnvelope1 - Required 1..1 |
Extensibility and generalization considerations
To facilitate generalized design patterns in the system, the SecuritiesAccountModificationRequestV01 implementation follows a specific implementaiton pattern. First of all, SecuritiesAccountModificationRequestV01 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, SecuritiesAccountModificationRequestV01Document implements IOuterDocument. Because SecuritiesAccountModificationRequestV01 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type SecuritiesAccountModificationRequestV01.

class IOuterRecord
SecuritiesAccountModificationRequestV01 --|> IOuterRecord : Implements
SecuritiesAccountModificationRequestV01Document --|> IOuterDocument~SecuritiesAccountModificationRequestV01~ : Implements
class IOuterDocument~SecuritiesAccountModificationRequestV01~ {
SecuritiesAccountModificationRequestV01 Message
}
Document wrapper for serialization
The only real purpose SecuritiesAccountModificationRequestV01Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:reda.023.001.01’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using SecuritiesAccountModificationRequestV01.ToDocument() method. The returned SecuritiesAccountModificationRequestV01Document value will serialize correctly according to ISO 20022 standards.
