Hi,
I'm having the same issue. My PI User has accessed the Data Archiving Services (http://host:50000/DataArchivingService/DAS) however when I access the RWB > Message Monitoring > Adapter Engine - Archive, still getting this error:
Cannot read archived messages; reason: Reading Messages from Archive failed. Reason: com.sap.archtech.archconn.exceptions.ArchServiceException: Could not check index. Reason: 401:Unauthorized
Any ideas?
thank you very much!
