Prior to Oracle 12c, you will probably only use DML error logging during direct path loads, since conventional path loads become very slow when using it. DML Error Logging Limitations DML error logging is not supported for nonscalar data types. Removing the NOT NULL constraint allows the mapping to run, which means that (and I remember this from when I first tried out data rules) it won't protect you from an SET TIMING ON TRUNCATE TABLE dest; INSERT INTO dest SELECT * FROM source LOG ERRORS INTO err$_dest ('INSERT NO-APPEND') REJECT LIMIT UNLIMITED; 99998 rows created.
Elapsed: 00:00:03.13 OK, around 3 seconds, which compares well with the 5 seconds in my 10gR2 test. You can define error tables for tables, views, and materialized views only. As a quick recap, Warehouse Builder from 10.2.0.3 onwards lets you enter an "Error Table" name for each target table in a mapping, wherapon it will insert a LOG ERRORS clause

You can modify this value by setting the Maximum number of errors configuration property of the mapping. The kicker though is that mappings using data rules then run only in row-based, PL/SQL mode, which when all things are considered usually runs a bit slower than set-based code.
The messages are displayed in the Validation Results window.

By following this book, you can use Oracle Warehouse Builder in the best possible way and maximize your learning potential.
It's within a margin of error though so I wouldn't read too much into this. Adding the DML error logging clause allows us to complete the insert of the valid rows. You can also select the types of logs to store. Let's run the first one again, take off the LOG ERRORS clause but remove the rows that could cause an error.
So, how does this all relate to Warehouse Builder then? On Windows, the agent logs are displayed in the Design Center console. Until OWB 10.2.0.3 this was only possible with row based mapping code, now it is possible in set based mode also.Warehouse Builder provides error logging for the tables, views, and materialized Elapsed: 00:00:04.21 OK, it's back to four seconds.
