Every database vendor's bulk load program is different but they all output some information which DataMigrator captures and copies to its own log (etllog). So you should see the it there.
It also analyzes the information and if it appears that the bulk load did not complete successfully it reports that which is the message that you are seeing.
If you need further information for debugging you could run the flow with traces enabled and then review the traces. Or you could set TEMPERASE off so that the intermediate files are not deleted from the temporary directory so that you can review them.
