If the quality issues fields are NULL, the record is not an exception. When any quality issue contains text or it contains an empty string, the record is an exception. Verify that a quality issue port contains null values when a field has no error. If the quality issue ports contain blanks instead of null values then the Exception transformation flags every record as an exception. When a user needs to correct the issues in the Analyst tool, the user cannot filter the exceptions by data quality issue.
