    Cause: Inheritance Issue: The method ExistenceCheck is defined in a superclass (or interface) but has not been overridden in the subclass where it is being called. Abstract Method: If ExistenceCheck is an abstract method in the superclass, it must be implemented in any concrete subclass. Interface Implementation: If the class implements an interface that includes the ExistenceCheck method, it must provide an implementation for that method.
    Solution: Redefine the Method: Go to the subclass where the error occurs and implement the ExistenceCheck method. Ensure that the method signature matches that of the superclass or interface. METHOD if_your_interface~ExistenceCheck. " Your implementation here ENDMETHOD. Check Class Hierarchy: Review the class hierarchy
