camt.037.001.03

Scope The Debit Authorisation Request message is sent by an account servicing institution to an account owner. This message is used to request authorisation to debit an account. Usage The Debit Authorisation Request message must be answered with a Debit Authorisation Response message. The Debit Authorisation Request message can be used to request debit authorisation in a:

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
%% DebitAuthorisationRequestV03 recursion level 0 with max 0
DebitAuthorisationRequestV03 *-- "1..1" CaseAssignment2 : Assignment
DebitAuthorisationRequestV03 *-- "1..1" Case2 : Case
DebitAuthorisationRequestV03 *-- "1..1" IUnderlyingTransaction1Choice : Underlying
DebitAuthorisationRequestV03 *-- "1..1" DebitAuthorisationDetails3 : Detail

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

Assignment building block

Identifies the assignment of an investigation case from an assigner to an assignee. Usage: The Assigner must be the sender of this confirmation and the Assignee must be the receiver. Set of elements used to represent the assignment of a case to a party. For comparison, see the ISO20022 official specification

CaseAssignment2 members

Member name Description Data Type / Multiplicity
Identification Uniquely identifies the case assignment. IsoMax35Text - Required 1..1
Assigner Party who assigns the case. Usage: This is also the sender of the message.
Assignee Party to which the case is assigned. Usage: This is also the receiver of the message.
CreationDateTime Date and time at which the assignment was created. IsoISODateTime - Required 1..1

Case building block

Identifies the investigation case. Set of elements used to identify a case. For comparison, see the ISO20022 official specification

class Case2{
    Identification IsoMax35Text

Case2 members

Member name Description Data Type / Multiplicity
Identification Uniquely identifies the case. IsoMax35Text - Required 1..1
Creator Party that created the investigation case. IParty7Choice - Required 1..1
ReopenCaseIndication Indicates whether or not the case was previously closed and is now re-opened. IsoYesNoIndicator - Optional 0..1

Underlying building block

Identifies the underlying payment instructrion. Specifies the details of the underlying transaction on which the investigation is processed. For comparison, see the ISO20022 official specification

Detail building block

Detailed information about the request. Provides the reason for requesting a debit authorisation as well as the amount of the requested debit. For comparison, see the ISO20022 official specification

DebitAuthorisationDetails3 members

Member name Description Data Type / Multiplicity
CancellationReason Specifies the reason for the cancellation request. ICancellationReason2Choice - Required 1..1
AmountToDebit Amount of money requested for debit authorisation. IsoActiveOrHistoricCurrencyAndAmount - Optional 0..1
ValueDateToDebit Value date for debiting the amount. IsoISODate - Optional 0..1
AdditionalCancellationReasonInformation Further details on the cancellation request reason. IsoMax105Text - Unknown 0..0

Extensibility and generalization considerations

To facilitate generalized design patterns in the system, the DebitAuthorisationRequestV03 implementation follows a specific implementaiton pattern. First of all, DebitAuthorisationRequestV03 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, DebitAuthorisationRequestV03Document implements IOuterDocument. Because DebitAuthorisationRequestV03 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type DebitAuthorisationRequestV03.

classDiagram
    class IOuterRecord
    DebitAuthorisationRequestV03 --|> IOuterRecord : Implements
    DebitAuthorisationRequestV03Document --|> IOuterDocument~DebitAuthorisationRequestV03~ : Implements
    class IOuterDocument~DebitAuthorisationRequestV03~ {
        DebitAuthorisationRequestV03 Message
     }

Document wrapper for serialization

The only real purpose DebitAuthorisationRequestV03Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:camt.037.001.03’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using DebitAuthorisationRequestV03.ToDocument() method. The returned DebitAuthorisationRequestV03Document value will serialize correctly according to ISO 20022 standards.
