How To Fix OL662 - Method 'ExistenceCheck' is not redefined

OL662 - Overview

• Message type: E = Error

• Message class: OL - Workflow object types: Run-time system

• Message number: 662

• Message text: Method 'ExistenceCheck' is not redefined

What causes this issue?

The method 'ExistenceCheck' is executed automatically in the
instantiation. To avoid problems during instantiation, you should
ensure that this method is implemented correctly.
In this case, the method is inherited and not redefined. This suggests
that the method has only the default implementation from the interface
IFSAP. The existence check is not yet implemented.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Please check whether the method 'ExistenceCheck' carries out a correct
existence check on the current object.
If this is not the case, please implement the method.

• What is the cause and solution for SAP error message OL662 - Method 'ExistenceCheck' is not redefined ?

  The SAP error message OL662, which states "Method 'ExistenceCheck' is not redefined," typically occurs in the context of ABAP programming, particularly when dealing with class methods in Object-Oriented ABAP. This error indicates that the method ExistenceCheck is expected to be redefined in a subclass but has not been implemented.
  
  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
