Oracle Error PLS-00649: method “string” can be overridden only once per object type

Oracle Error Message

PLS-00649: method “string” can be overridden only once per object type

Reason for the Error

User tried to override the method more than once in the same subtype.

Solution

Either make this an extra overload by removing the OVERRIDING keyword where the method signature is different. The argument types should be reconsidered otherwise.
