Whenever configuration items (CIs) are updated through a deduplication task, the discovered items (DIs) that are related to those CIs are also updated. The vulnerable items (VIs) and detections are also updated with the
CI.

For more information, see [CI changes for discovered items](https://servicenow-prod.fluidtopics.net/D4NLUAp0jrLT1oLHbhXSxQ "When a configuration item (CI) on a discovered item (DI) changes, the impacted detections and vulnerable items (VIs) are updated. The risk score, assignment rules, group rules, and remediation target rule are reevaluated.").
