I am running Hardware Reconciliation in IT Asset Manager. I am getting duplicate messages similar to the below message
Discovered asset id 07CABE51CDEBFF44A184D3C1BA520D5E name DR45WS0Y637 matches 2 owned assets.
If Reconciliation Engine is matched on Serial Number, this message says that there is more than one owned asset with the same serial number.
If the serial number is not displayed in the log, query the al_discovered_hardware table for the asset name in the message.
You can then search for assets with the same serial number. Review the assets and delete or inactivate one, through the GUI, to allow reconciliation to match against only one asset.
