• What is the cause and solution for SAP error message OO602 - Implementation of method & deleted ?

  The SAP error message OO602, which states "Implementation of method & deleted," typically occurs in the context of Object-Oriented Programming (OOP) in ABAP (Advanced Business Application Programming). This error indicates that a method that is being called has been deleted or is no longer implemented in the class definition.
  Cause:
  
  Deleted Method: The method that is being invoked has been removed from the class implementation.
  Changes in Class Definition: The class definition may have been modified, and the method was either renamed or removed.
  Inconsistent Code: There may be inconsistencies between the class definition and the implementation, especially if the code was modified without proper updates to all references.
  Transport Issues: If the class was transported from one system to another, the transport might not have included the latest version of the method.
  
  Solution:
  
  Check Class Implementation: Verify the class definition and implementation to ensure that the method exists. You can do this by navigating to the class in the ABAP Workbench (SE80 or SE24).
  Restore Method: If the method was deleted unintentionally, you may need to restore it from a backup or version control if available.
  Update References: If the method has been renamed or its signature has changed, update all references to the method in your code accordingly.
  Transport Request: If the issue is due to a transport problem, ensure that the transport request containing the latest version of the class is correctly imported into the target system.
  Check for Active Versions: Make sure that the active version of the class is the one you expect. Sometimes, changes may not be activated properly.
  Debugging: Use the debugger to trace where the method is being called and confirm that it is indeed the correct method being referenced.
