Processing Acknowledgment Messages

The acknowledgment is sent by the MT service to the Logical Terminal to confirm the receipt of a message and its safe storage by the service.

If an ACK is returned, the message is accepted by the MT service for delivery to its destination. If a NAK is returned, the message is safely stored, but failed to deliver. The structure of an ACK or a NAK message is the same, except that the value of tag 451 is in the text block of an Acknowledgment message. 0 indicates the ACK, and 1 indicates the NAK.

MT acknowledgment messages are parsed using the FIN_Acknowledgment schema. This schema loads automatically after you create a Load SWIFT MT schema shared resource. The plug-in supports the parsing and rendering of the ACK and NAK messages.

    Procedure
  1. Open the process that you want to process the acknowledge messages.
    Note: Ensure that you have created a Load SWIFT MT schema shared resource in this process.
  2. Click the General tab of the Parse SWIFT MT activity or Render SWIFT MT activity.
  3. In the SWIFT Message Schema field, click and select the Message_FIN_Acknowledgement message schema.
  4. Save the process.
