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
%% DebitAuthorisationRequest recursion level 0 with max 0
DebitAuthorisationRequest *-- "1..1" CaseAssignment : Assignment
DebitAuthorisationRequest *-- "1..1" Case : Case
DebitAuthorisationRequest *-- "1..1" PaymentInstructionExtract : Underlying
DebitAuthorisationRequest *-- "1..1" DebitAuthorisationDetails : Detail

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

Assignment building block

Identifies the case assignment. Represents the assignment of a case to a party. Assignment is a step in the overall process of managing a case. For comparison, see the ISO20022 official specification

classDiagram
   direction tb
%% CaseAssignment recursion level 0 with max 1
class CaseAssignment{
    Identification IsoMax35Text
    Assigner IsoAnyBICIdentifier
    Assignee IsoAnyBICIdentifier
    CreationDateTime IsoISODateTime
}

CaseAssignment members

Member name Description Data Type / Multiplicity
Identification Identification of an assignment within a case. IsoMax35Text - Required 1..1
Assigner Party that assigns the case to another party. This is also the sender of the message. IsoAnyBICIdentifier - Required 1..1
Assignee Party that the case is assigned to. This is also the receiver of the message. IsoAnyBICIdentifier - Required 1..1
CreationDateTime Date and time at which the assignment was created. IsoISODateTime - Required 1..1

Case building block

Identifies the case. Information identifying a case. For comparison, see the ISO20022 official specification

classDiagram
   direction tb
%% Case recursion level 0 with max 1
class Case{
    Identification IsoMax35Text
    Creator IsoAnyBICIdentifier
    ReopenCaseIndication IsoYesNoIndicator
}

Case members

Member name Description Data Type / Multiplicity
Identification Unique id assigned by the case creator. IsoMax35Text - Required 1..1
Creator Party that created the case. IsoAnyBICIdentifier - Required 1..1
ReopenCaseIndication Set to yes if the case was closed and needs to be re-opened. IsoYesNoIndicator - Optional 0..1

Underlying building block

Identifies the underlying payment instructrion. Details of a payment instruction. The information contained in this component is sufficient to retrieve a payment instruction. For comparison, see the ISO20022 official specification

classDiagram
   direction tb
%% PaymentInstructionExtract recursion level 0 with max 1
class PaymentInstructionExtract{
    AssignerInstructionIdentification IsoMax35Text
    AssigneeInstructionIdentification IsoMax35Text
    CurrencyAmount IsoCurrencyAndAmount
    ValueDate IsoISODateTime
}

PaymentInstructionExtract members

Member name Description Data Type / Multiplicity
AssignerInstructionIdentification Identification of the payment instruction (eg, field 20 of an MT 103) when meaningful to the case assigner. IsoMax35Text - Optional 0..1
AssigneeInstructionIdentification Identification of the payment instruction (eg, field 20 of an MT 103) when meaningful to the case assignee. IsoMax35Text - Optional 0..1
CurrencyAmount Amount of the payment. Depending on the context it can be either the amount settled (UnableToApply) or the instructed amount (RequestToCancel, RequestToModify, ClaimNonReceipt). IsoCurrencyAndAmount - Optional 0..1
ValueDate Value date of the payment. IsoISODateTime - Optional 0..1

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

classDiagram
   direction tb
%% DebitAuthorisationDetails recursion level 0 with max 1
class DebitAuthorisationDetails{
    CancellationReason CancellationReason1Code
    AmountToDebit IsoCurrencyAndAmount
    ValueDateToDebit IsoISODate
}

DebitAuthorisationDetails members

Member name Description Data Type / Multiplicity
CancellationReason Indicates the reason for cancellation. CancellationReason1Code - Required 1..1
AmountToDebit Amount of money to be moved between the debtor and creditor, before deduction of charges, expressed in the currency as ordered by the initiating party. IsoCurrencyAndAmount - Optional 0..1
ValueDateToDebit Value date for debiting the amount. IsoISODate - Optional 0..1

Extensibility and generalization considerations

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

classDiagram
    class IOuterRecord
    DebitAuthorisationRequest --|> IOuterRecord : Implements
    DebitAuthorisationRequestDocument --|> IOuterDocument~DebitAuthorisationRequest~ : Implements
    class IOuterDocument~DebitAuthorisationRequest~ {
        DebitAuthorisationRequest Message
     }

Document wrapper for serialization

The only real purpose DebitAuthorisationRequestDocument serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:camt.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 DebitAuthorisationRequest.ToDocument() method. The returned DebitAuthorisationRequestDocument 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.
