AccountSwitchTechnicalRejectionV01

acmt.037.001.01

The AccountSwitchTechnicalRejection message is sent by the account switch servicer to the new account servicer when it has not been able to validate a previously sent 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
%% AccountSwitchTechnicalRejectionV01 recursion level 0 with max 0
AccountSwitchTechnicalRejectionV01 *-- "1..1" MessageIdentification1 : MessageIdentification
AccountSwitchTechnicalRejectionV01 *-- "1..1" AccountSwitchDetails1 : AccountSwitchDetails
AccountSwitchTechnicalRejectionV01 *-- "0..1" SupplementaryData1 : SupplementaryData
  

Now, we will zero-in one-by-one on each of these building blocks.

MessageIdentification building block

Unique identification for the message. Identifies a message by a unique identifier and the date and time when the message was created by the sender. For comparison, see the ISO20022 official specification

   direction tb
%% MessageIdentification1 recursion level 0 with max 1
class MessageIdentification1{
    Identification IsoMax35Text
    CreationDateTime IsoISODateTime
}
  

MessageIdentification1 members

Member name Description Data Type / Multiplicity
Identification Identification of the message. IsoMax35Text - Required 1..1
CreationDateTime Date of creation of the message. IsoISODateTime - Required 1..1

AccountSwitchDetails building block

Contains information about the details of the account switch, including reasons for the technical rejection of the account switch. Details of the account switch, including its status and any response codes. For comparison, see the ISO20022 official specification

AccountSwitchDetails1 members

Member name Description Data Type / Multiplicity
UniqueReferenceNumber Unique number that provides unique and unambiguous identification of the account switch. IsoMax35Text - Required 1..1
RoutingUniqueReferenceNumber Unique number that provides unique and unambiguous identification of the account switch. Usage: Where one or more account switches have taken place since the original account switch this field contains the unique number that relates to the switch that transferred the account to the latest new account servicer. IsoMax35Text - Required 1..1
SwitchReceivedDateTime Date and time that the request was received by the central switch service, populated by the central switch service only. IsoISODateTime - Optional 0..1
SwitchDate Date on which the account switch is expected to have completed. The value is the same as the targeted switch date if the switch completes in the expected timeline. IsoISODate - Optional 0..1
SwitchType Indicates whether the account switch is a full switch or a partial switch. Usage: A full switch indicates the transfer of the full balance of the account and associated payment mandates. A partial switch indicates the transfer of certain payment mandates to a new account. SwitchType1Code - Required 1..1
SwitchStatus State of the account switch at the time the message is sent. SwitchStatus1Code - Optional 0..1
BalanceTransferWindow Identifies the processing window in which the balance transfer will be processed on the day of the account switch. BalanceTransferWindow1Code - Optional 0..1
Response Response code and additional information. ResponseDetails1 - Unknown 0..0

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 recursion level 0 with max 1
class SupplementaryData1{
    PlaceAndName IsoMax350Text
}
SupplementaryData1 *-- "1..1" IsoSupplementaryDataEnvelope1 : Envelope
%% IsoSupplementaryDataEnvelope1 recursion level 1 with max 1
  

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 AccountSwitchTechnicalRejectionV01 implementation follows a specific implementaiton pattern. First of all, AccountSwitchTechnicalRejectionV01 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, AccountSwitchTechnicalRejectionV01Document implements IOuterDocument. Because AccountSwitchTechnicalRejectionV01 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type AccountSwitchTechnicalRejectionV01.

classDiagram
    class IOuterRecord
    AccountSwitchTechnicalRejectionV01 --|> IOuterRecord : Implements
    AccountSwitchTechnicalRejectionV01Document --|> IOuterDocument~AccountSwitchTechnicalRejectionV01~ : Implements
    class IOuterDocument~AccountSwitchTechnicalRejectionV01~ {
        AccountSwitchTechnicalRejectionV01 Message
     }
  

Document wrapper for serialization

The only real purpose AccountSwitchTechnicalRejectionV01Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:acmt.037.001.01’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using AccountSwitchTechnicalRejectionV01.ToDocument() method. The returned AccountSwitchTechnicalRejectionV01Document value will serialize correctly according to ISO 20022 standards.

Sample of message format

This is an abbreviated version of what the message should look like.

<Document xmlns="urn:iso:std:iso:20022:tech:xsd:acmt.037.001.01">
    <AcctSwtchTechRjctn>
        <MsgId>
            <!-- MessageIdentification inner content -->
        </MsgId>
        <AcctSwtchDtls>
            <!-- AccountSwitchDetails inner content -->
        </AcctSwtchDtls>
        <SplmtryData>
            <!-- SupplementaryData inner content -->
        </SplmtryData>
    </AcctSwtchTechRjctn>
</Document>
