Oracle Error Message
KUP-04060: field string referenced by lobfile column string not found
Reason for the Error
The LOBFILE transform for the named column referenced a field for either the directory object portion or the name portion of the LOBFILE. However, that field did not exist anywhere in the definition of the data file.
Solution
Verify that the LOBFILE clause is specified correctly. Also verify that the field definitions for the data file are correct.
