26.1.1.1 Incoming Negative Acknowledgement Processing

This topic provides the sequence of processing steps for NACKed messages, including negative acknowledgement processing, message repair, and message resend procedures.

  • After receiving the negative acknowledgment and matching with the original outbound SWIFT CBPRPlus or TARGET2 ISO message, the system logs the original Outbound message in the Outbound Messages Repair Queue.

    Note:

    Negative Acknowledgement message refers to NACK from SWIFT FINPlus or Interact and Admi.007 (Receipt Acknowledgement) from TARGET2.
  • A new queue reference is generated, and the below fields of the outbound message get populated.
    • Original Transaction Reference as Reference Number
    • UETR
    • Message Format (Value as MX)
    • SWIFT Message Type
    • Network
    • Branch
    • Receiver (Instructed Agent or To BIC)
    • Currency
    • Amount
    • Acknowledgement Status
    • Network Acknowledgement Status
    • Current Status as 'Pending'

    Note:

    If the NACKed message is embedded in the DataPDU header, the DataPDU gets removed and the payload (Business Application Header and payment message) is logged in the Message Repair Queue.
