# Reapply CI lookup rules on selected discovered items

Reapply the configuration item \(CI\) lookup rules on selected discovered items from the discovered item list view select actions. If the CI changes after you reapply the rules, the discovered items are updated with the new CI and impacted detections. Vulnerable items are also updated.

## Before you begin

Roles required: admin

## About this task

For more information, see [CI changes for discovered items](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/security-management/vulnerability-response/reapply-discovered-items-ci-changes.md).

For more information about the concepts of CI matching and the CMDB, discovered item lookup, rule-based identification, and other detailed information about how CI matching works, see the [CI matching in Vulnerability Response \[KB0998706\] article](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0998706) in the HI Knowledge Base.

## Procedure

1.  Navigate to **All** > **Security operations** > **CMDB** > **Discovered Items**.

2.  Select the required discovered items and click **Action on selected rows**.

    \[Omitted image "reapply-action-di.png"\] Alt text: Reapply CI lookup rules on Discovered Items.

3.  From the list, select **Reapply CI lookup rules**.

    **Note:**

    Starting with Vulnerability Response v24.0.6, you can skip the reapplication of CI lookup rules on discovered items with the substate ‘CI Decommissioned’ by enabling the system property **sn\_sec\_cmn.skipItemsWithCIDecommissioned**.

    The rules are reapplied on these discovered items.

4.  Click **View status** in the message.

    The status displays on the background job form.

    **Note:** In the **Notes** field, the `Discovered items could not be process due to exception` attribute with a non-zero value indicates that there is an error or exception while reapplying a CI look up rule. Check the system logs for more details.

5.  Reapply only applies to items scanned within the last 90 days based on the **last\_scan\_date, last\_comp\_scan\_date, non\_infra\_last\_scan\_date, non\_infra\_last\_comp\_scan\_date** column.

    Added ci\_lifecycle\_status\_source \(scope = sn\_sec\_cmn\) system property for configuring Ci lifecycle status columns \(e.g., Install Status, Operational Status\). You can configure additional columns for retiring CIs.

    Columns are added to the background job list view:

    -   Elapsed Time\(ms\): The time required for processing the background job.
    -   Items Processed: The number of items processed till now.
    -   Total Items to be Processed: The total number of items remaining to be processed.
    -   Time Until Completion\(ms\): The time remaining until the background job is processed. These columns provide visibility into job progress, these columns are available for each form view for you to add as per requirement.
