Item Reconciliation during item import from ZENworks
Based on your requirement, you can enable Item reconciliation to avoid the creation of duplicate items or to reconcile with an existing item based on certain criteria. For more information see the Item Reconciliation section.
If there is more than one configuration to the same ZENworks or an older configuration is deleted and a new configuration is created pointing to the same ZENworks, then you might end up with duplicate items if reconciliation is not enabled or reconciliation criteria is not met.
