      ChoiceDescription
      Use the Duplicate CI Remediator

      Use the Duplicate CI Remediator built on Core UI to remediate the task.

      To continue with this choice of remediation, see Remediate a de-duplication task (manual).
      Use the Duplicate CI Remediator (AI)

      Use the De-duplication task resolution assistant skill to make suggestions for the de-duplication options, instead of manually selecting these options.

      The De-duplication task resolution assistant skill skips directly to the final dashboard of the Duplicate CI Remediator where you can review the selections made by the skill.
      Use the Duplicate CI Remediator in Restricted Mode

      Appears only if the glide.duplicate_ci_remediator.enable_restricted_mode system property is set to true. You might need to use this option if remediation is blocked because loading the de-duplication task times out. This option might be relevant when there is a large number of related items associated with a de-duplication task, allowing remediation to continue with the limited features in a restricted mode. For more information about using this option to restrict the use of related items in de-duplication remediation and allow remediation to proceed, see Using restricted mode within the Duplicate CI Remediator [KB1542272].

      To continue with this choice, see Remediate a de-duplication task (manual). Skip to step #5 in the procedure.
      Remediate using a template

      Use a de-duplication template to remediate the task.

      To continue with this choice of remediation: In the Remediate dialog box, select the Library and the Template to use for the remediation, and then select Remediate.

    What to do next

    On the task form:
    • Track the progress and the details of remediation in the Activity stream until remediation is complete.
