Does harvests SCM stores error messages in a Harvest´s database table.
Harvest does not store the errors in any table of the database. Harvest store errors messages in the %CA_SCM_HOME%\log folder. It will depends on where the error happens. You've got *HBroker*.log, *HServer*.log for the broker, *HAgent*.log for the agent, hrefresh logs Also workbench's output log shows information. And not all the errors are tracked it will also depende of the logging level that you have configure in the broker.
