What type of message is used when a record is determined to be invalid?

A cancellation message is used when a record is determined to be invalid because it serves the purpose of formally removing or negating that record from the data system. This type of message indicates that a previously entered record should no longer be referenced or acted upon, ensuring that all users and systems have accurate and up-to-date information. The cancellation process is essential for maintaining data integrity and preventing potential confusion or errors that may arise from relying on outdated or incorrect records.

Other message types such as locate messages are typically employed to search for specific records, administrative messages might deal with system updates or changes, and confirmation messages validate an action taken, none of which directly address the need to invalidate a record. Therefore, the function of a cancellation message is crucial in the context of managing data accuracy within the system.
