Return Message Generation refers to the process where the system generates a message in response to a payment transaction or instruction that has failed or encountered an issue during processing.

The return transaction XML is generated and validated upon successful return transaction processing. The original transaction details populated in the return message (pacs.004) is having the original transaction details as received (pacs.008/pacs.009) without considering any enrichment done by the system like account/bank redirection, special character replacement or repair done for the transaction.

From the R-Transaction tab in Inbound pacs.008/pacs.009 transaction view screens user can view the return message.
