A core alert highlights a specific issue based on the failure of a single validation rule for a record being evaluated by a status processor.
The core alert is stored as part of the evaluated record's Validation Status.

A core alert may be one of two types:

• Warning
• Advice (Alert Type)

Each core alert can be reviewed and acknowledged by a user (see manage_sis_work_items) and has a status that highlights whether or not the identified issue is being reviewed:

• Unacknowledged (Acknowledgement Status) – no one has acknowledged that they are working to address this issue.
• InProgress (Acknowledgement Status) – someone has identified that they are currently investigating this issue.
• Acknowledged (Acknowledgement Status) – applied only to Advice, this status identifies that the issue was reviewed and the data is correct as-is (no changes are required).
• Overridden (Acknowledgement Status) – applied only to Warnings, this status identifies that the issue was reviewed and the Warning is being overridden as the Warning is blocking downstream processing.
