In the Link Rules application, you can create link rules to add to a reconciliation task. You can create link rule records from the List tab or from the Link Rule tab in the application.
Link rules are often based on unique identifiers. The attribute most commonly used to link assets and deployed assets is a serial number or asset tag. The attribute most commonly used to link configuration items (CIs) with actual CIs is ACTCINUM, the actual CI number.
You can add the link rules that you create to reconciliation tasks that you create in the Reconciliation Tasks application.
