PLS-00484: redundant exceptions string and string must appear in same exception handler

PLS-00484: redundant exceptions string and string must appear in same exception handler

Cause: Using the EXCEPTION_INIT pragma, different exceptions were initialized to the same Oracle error number; then, they were referenced in different exception handlers within the same exception-handling part. Such references conflict.

Action: Remove one of the exceptions or initialize it to a different Oracle error number.
