If Unity encounters an error during a Read request, it checks for the error code and responds as follows.

Listed in the Error Profile and set to Retry Resubmits the query to the same Teradata Database system.
Listed in the Error Profile and set to Exit Session closes on all Teradata Database systems.
Not listed in the Error Profile Error is returned to the client.
