Replication jobs were reaching 100% but failures were reported. The replication reports were unable to identify the names of the items that failed.
The only clue to the failure were two warnings in the SMP logs of the Child server replicating up to the parent.

The log entries identified two data classes (in this case custom data classes) that were replicable at one time but could not be replicated because their table name could not be resolved.
For an unknown reason the data classes had gotten renamed to a blank name, and the data class name is what is used to determine the table name to query for rows to replicate up. Since the name was blank this could not be done.
To test to see if the condition exists run the following SQL against the database. It will identify the GUID of a data class that cannot be replicated.
SELECT i.Guid, i.Name, lr._eventTime as LastReplication, lr.StatusCode, lr.StatusText
FROM vItem i
JOIN Evt_NS_Object_Replication_Status lr on lr.LocalGuid = i.Guid
WHERE ((ClassGuid = '31ECB8A5-78DD-48E5-87D1-599140332734' -- Altiris.Inventory.ManageCustomDataClasses
and (i.Attributes & 4) = 0
and lr.StatusCode <> 0))
OR (lr.StatusCode = -2147212796 and lr.StatusText = 'Table name could not be resolved.')
order by lr._eventTime desc
In the case sited one of the data classes was broken and could not be found in the console, but were still present in the database enough to cause the replication engine to try and send them up to the parent.
