Description
Lookup stages have a ‘Condition Not Met’ setting which describes what happens when a key lookup fails. Options are:
Continue - The fields from that link are set to NULL if the field is nullable, or to a default value if not, and processing continues
Drop - Drops the row and continues with the next lookup
Fail - Causes the job to issue a fatal error and stop
Reject - Sends the row to the reject link
By default Lookup stages are configured to Fail should a key lookup fail. This unexpected job abort is, in most cases, not the behaviour the developer intended. These lookup fails should be handled gracefully in the ETL job.
Actions
Reconfigure your Lookup stage so that reference links are not set to abort the job should a key lookup fail.
