    Error
    Warning

    Selecting this option can cause the MTO to be flooded with messages in the following situations:

    • The Default processing option for a non-serial transaction is 4 Requeue, and processing causes that transaction to acquire USTOP status.
    • The Default processing option for a serial transaction is 1 IMS, 3 Suspend, or 4 Requeue, and processing causes that transaction to acquire USTOP status.
  6. Do not send DFS555I–Activate or deactivate this option to indicate whether to issue the DFS555I message. If activated, the DFS555I message is not issued. If deactivated, the DFS555I message is issued. Type a slash (/) in the selection field next to this field to indicate use of this option; otherwise, leave this field blank.
