Scope This message is sent by an account owner to an account servicer.
The account owner will generally be:
- a central securities depository participant which has an account with a central securities depository or a market infrastructure
- an investment manager which has an account with a custodian acting as accounting and/or settlement agent.
It is used to request the modification of non core business data (matching or non-matching) information in a pending or settled instruction. It can also be used for the enrichment of an incomplete transaction.
Usage The modification must only contain the data to be modified. The message may also be used to:
- re-send a message sent by the account owner to the account servicer,
- provide a third party with a copy of a message being sent by the account owner for information,
- re-send to a third party a copy of a message being sent by the account owner for information using the relevant elements in the Business Application Header.
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 SecuritiesSettlementTransactionModificationRequestV05 implementation follows a specific implementaiton pattern. First of all, SecuritiesSettlementTransactionModificationRequestV05 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, SecuritiesSettlementTransactionModificationRequestV05Document implements IOuterDocument. Because SecuritiesSettlementTransactionModificationRequestV05 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type SecuritiesSettlementTransactionModificationRequestV05.

}
Document wrapper for serialization
The only real purpose SecuritiesSettlementTransactionModificationRequestV05Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:sese.038.001.05’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using SecuritiesSettlementTransactionModificationRequestV05.ToDocument() method. The returned SecuritiesSettlementTransactionModificationRequestV05Document value will serialize correctly according to ISO 20022 standards.
