AdditionalPaymentInformationV08

camt.028.001.08

Scope The AdditionalPaymentInformation message is sent by an account servicing institution to an account owner. This message is used to provide additional or corrected information on a payment instruction or statement entry, in order to allow reconciliation. Usage The AdditionalPaymentInformation message provides elements which are usually not reported in a statement or advice (for example full remittance information or identification of parties other than the account servicing institution and the account owner). It complements information about a payment instruction that has already been received, in the form of one or several entries of the original payment instruction. The AdditionalPaymentInformation message covers one and only one original payment instruction. If several payment instructions need further details, multiple AdditionalPaymentInformation messages must be used, one for each of the payment instructions. The AdditionalPaymentInformation message may be used as a result of two investigation processes and in a way outlined below.

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

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. Represents the assignment of a case to a party. For comparison, see the ISO20022 official specification

Extensibility and generalization considerations

To facilitate generalized design patterns in the system, the AdditionalPaymentInformationV08 implementation follows a specific implementaiton pattern. First of all, AdditionalPaymentInformationV08 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, AdditionalPaymentInformationV08Document implements IOuterDocument. Because AdditionalPaymentInformationV08 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type AdditionalPaymentInformationV08.

classDiagram
    class IOuterRecord
    AdditionalPaymentInformationV08 --|> IOuterRecord : Implements
    AdditionalPaymentInformationV08Document --|> IOuterDocument~AdditionalPaymentInformationV08~ : Implements
    class IOuterDocument~AdditionalPaymentInformationV08~ {
        AdditionalPaymentInformationV08 Message
     }
  

Document wrapper for serialization

The only real purpose AdditionalPaymentInformationV08Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:camt.028.001.08’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using AdditionalPaymentInformationV08.ToDocument() method. The returned AdditionalPaymentInformationV08Document value will serialize correctly according to ISO 20022 standards.

  definition="Scope&#xD;&#xA;The AdditionalPaymentInformation message is sent by an account servicing institution to an account owner.&#xD;&#xA;This message is used to provide additional or corrected information on a payment instruction or statement entry, in order to allow reconciliation.&#xD;&#xA;Usage&#xD;&#xA;The AdditionalPaymentInformation message provides elements which are usually not reported in a statement or advice (for example full remittance information or identification of parties other than the account servicing institution and the account owner). It complements information about a payment instruction that has already been received, in the form of one or several entries of the original payment instruction.&#xD;&#xA;The AdditionalPaymentInformation message covers one and only one original payment instruction. If several payment instructions need further details, multiple AdditionalPaymentInformation messages must be used, one for each of the payment instructions.&#xD;&#xA;The AdditionalPaymentInformation message may be used as a result of two investigation processes and in a way outlined below.&#xD;&#xA;- A ClaimNonReceipt workflow raised by the creditor or recipient of the payment: This means that the payment instruction has reached the creditor or beneficiary. The account owner needs further details or correct information for its reconciliation processes. The AdditionalPaymentInformation can be used to provide the missing information.&#xD;&#xA;- A RequestToModifyPayment workflow raised by the debtor or one of the intermediate agents upstream: When the payment instruction has reached its intended recipient and the modification does not affect the accounting at the account servicing institution, this AdditionalPaymentInformation message allows the account owner to receive further particulars or correct information about a payment instruction or an entry passed to its account.&#xD;&#xA;The AdditionalPayment Information message cannot be used to trigger a request for modification of a payment instruction activity. A RequestToModifyPayment message must be used. In other words, if a debtor or one of intermediate agent (excluding the account servicing institution of the creditor) realises the some information was missing in the original payment instruction, he should not use an AdditionalPaymentInformation but instead a RequestToModifyPayment message.&#xD;&#xA;It is assumed that when an account servicing institution sends out an AdditionalPaymentInformation message, the institution is fairly confident that this will resolve the case. Therefore it does not need to wait for a Resolution Of Investigation message. Neither does the account owner, or whoever receives the additional information, need to send back a ResolutionOfInvestigation message. Positive resolution in this case is implicit. Both parties are expected to close the case. In the event that the problem does not go away, a party can re-open the case."
