Mload error - Highest return code encountered = '23' - response (2) by dnoeth

Hi Cheeli,
in the UV table are not only duplicates, but also errors based on the MARK option in the DML label and errors during the update like numeric overflow.
When you don't care about duplicate row errors, etc., you might better use IGNORE instead of MARK.
The MLoad will not fail when there are errors in the UV table, but of course you should never drop an error table without investigating the cause of the errors. Did you check the errorcodes for those rows?
If you drop error tables without checking them your load process is faulty.
