Oracle Error Message
ORA-26748: The one-to-one transformation function string encountered the following error: string
Reason for the Error
The specified transformation function encountered an error.

Ensure that the function does not return an LCR that has a different type from the LCR which was passed to the function. Also ensure that the function does not return NULL. For DDL transformation functions, creating and returning a new DDL LCR is not allowed.
