The AccountMandateMaintenanceAmendmentRequest message is sent from an organisation to a financial institution as part of the account maintenance process. It is sent in response to a request from the financial institution to send additional information. Usage: this update is only about mandate information. If modification codes are not used: the organisation will specify under the “Mandate” and “Group” tags the complete information as it should be in the financial institution’s records after processing the update request. If modification codes are used (in that case, they must be used everywhere): the organisation will specify under the “Mandate” and “Group” tags which elements must be added, deleted, modified, or if they are unchanged. It is not possible to update the account characteristics or organisation information with this 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

Extensibility and generalization considerations
To facilitate generalized design patterns in the system, the AccountMandateMaintenanceAmendmentRequestV02 implementation follows a specific implementaiton pattern. First of all, AccountMandateMaintenanceAmendmentRequestV02 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, AccountMandateMaintenanceAmendmentRequestV02Document implements IOuterDocument. Because AccountMandateMaintenanceAmendmentRequestV02 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type AccountMandateMaintenanceAmendmentRequestV02.
classDiagram class IOuterRecord AccountMandateMaintenanceAmendmentRequestV02 --|> IOuterRecord : Implements AccountMandateMaintenanceAmendmentRequestV02Document --|> IOuterDocument~AccountMandateMaintenanceAmendmentRequestV02~ : Implements class IOuterDocument~AccountMandateMaintenanceAmendmentRequestV02~ { AccountMandateMaintenanceAmendmentRequestV02 Message }
Document wrapper for serialization
The only real purpose AccountMandateMaintenanceAmendmentRequestV02Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:acmt.018.001.02’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using AccountMandateMaintenanceAmendmentRequestV02.ToDocument() method. The returned AccountMandateMaintenanceAmendmentRequestV02Document value will serialize correctly according to ISO 20022 standards.
