CI identifiers will not match with CI's which have 'duplicate of' field populatedIssue When running a Discovery, if you are seeing no matches even when the target CI has the same criterion attribute values as the data from the Discovery, it is a possibility that the identification engine could be ignoring your target CI due to the 'duplicate of' field being populated on the target CI.ReleaseAnyResolutionTo resolve this, just remove the data in the 'duplicate of' field, the identification engine will not recognise this as a duplicate CI and will start matching and updating the target CI.
