Which type of message is transmitted to the entering agency when its record has been canceled by the FBI data integrity staff?

When a record is canceled by the FBI data integrity staff, the message transmitted to the entering agency is specifically an event message that indicates such a cancellation has occurred. This is denoted by the $.E format. The $.E message serves as a notification or signal that a previously entered record has been invalidated and is no longer valid within the system.

Understanding this format is crucial for agencies to maintain accurate and up-to-date records, as cancellations need to be communicated effectively to prevent any misuse or misunderstandings related to the status of that record. Other options do not properly reflect the specific type of message transmitted in this context.
