Hi Michal ,
We can authenticate suspicious pure urn id format EPC (pallet/case/unit) in the Supply chain using authenticate button in OER . If EPC is found in repository (OER) then it shows a message "known" else it shows "unknown".
And incase , if we also enter any parameter value along with EPC . e.g TID then OER checks for the matching parameter value against the EPC. If EPC is found and input parameter value matches with system value then it shows a message "known" else it shows "suspicious".
For every successful authentication , OER captures an AUTHENTICATION event against EPC .
