Error inserting null fields in Teradata (through JDBC)

Hi,

I'm trying to insert data in a Teradata database using PutDatabaseRecord processor. The process is fine until one record (input field) is null. Then the entire insertion batch get an error and do rollback of the transaction. 

Error capture: 

Attached the configuration info:

-Processor: 

-Pool: 

Any idea about how can I resolve this error? 

Thank you in advance,

Guillermo Chico
