Give me a practical example of EndToEndIdentification in the ISO20022 pacs.008 ? Who provides the information?

 A practical example of EndToEndIdentification in the ISO 20022 pacs.008 message is to link the payment to an invoice. The ordering party would assign a unique EndToEndIdentification to the payment instruction, and they would also include this identifier on the invoice. This would allow the beneficiary party to easily reconcile the payment to the invoice.

Another example of EndToEndIdentification is to link the payment to a purchase order. The ordering party would assign a unique EndToEndIdentification to the payment instruction, and they would also include this identifier on the purchase order. This would allow the beneficiary party to easily track the status of the order and to ensure that they have received the correct payment.

The EndToEndIdentification can be provided by either the ordering party or the beneficiary party. However, it is more common for the ordering party to provide the EndToEndIdentification, as they are the ones who are initiating the payment.

Here is an example of a pacs.008 message with an EndToEndIdentification:

In this example, the EndToEndIdentification is "ABC/4562/2015-09-08". This identifier could be linked to an invoice, a purchase order, or any other financial transaction.

The EndToEndIdentification can be a valuable tool for improving the efficiency and accuracy of payment processing. It can also help to reduce fraud and to improve the customer experience.

The difference between InstrId and EndToEndId in the above example is as follows:

• InstrId: The InstrId is a unique identifier for the payment instruction, as assigned by the ordering party. It is used to track the payment through the system and to resolve any disputes.

• EndToEndId: The EndToEndId is a unique identifier for the end-to-end transaction, as assigned by the ordering party or the beneficiary party. It is used to link the payment to other financial transactions, such as an invoice or a purchase order.

In the example, the InstrId is "BBBB/150928-CCT/JPY/123/1". This identifier is used to track the payment through the system from the ordering party to the beneficiary party.

The EndToEndId is "ABC/4562/2015-09-08". This identifier is used to link the payment to the invoice. This allows the beneficiary party to easily reconcile the payment to the invoice.

Another way to think about the difference between InstrId and EndToEndId is that the InstrId is a unique identifier for the payment instruction itself, while the EndToEndId is a unique identifier for the transaction that the payment is associated with.

The use of InstrId and EndToEndId is not mandatory in ISO 20022. However, it is highly recommended, as it can help to improve the efficiency and accuracy of payment processing.
