• What is the cause and solution for SAP error message CLUNDO002 - Undo at class level not possible for object & ?

  The SAP error message CLUNDO002 indicates that an undo operation at the class level is not possible for a specific object. This error typically arises in the context of object-oriented programming in ABAP, particularly when dealing with class instances and their states.
  Cause:
  The error can occur due to several reasons:
  
  Object State: The object you are trying to undo may not be in a state that allows for an undo operation. For example, if the object has already been deleted or is in a state that does not support undoing.
  Class Definition: The class may not have been defined properly to support undo operations. This could be due to missing methods or incorrect implementation of the undo functionality.
  Transaction Management: If the object is part of a transaction that has already been committed, it may not be possible to undo changes at the class level.
  Locking Issues: There may be locks on the object that prevent the undo operation from being executed.
  
  Solution:
  To resolve the CLUNDO002 error, consider the following steps:
  
  Check Object State: Ensure that the object is in a state that allows for an undo operation. If the object has been deleted or is otherwise not valid, you may need to recreate it or handle it differently.
  Review Class Implementation: Verify that the class is implemented correctly and that it includes the necessary methods for undo operations. Ensure that the undo method is properly defined and accessible.
  Transaction Handling: If the object is part of a transaction, ensure that the transaction has not been committed. If it has, you may need to implement a different approach to revert changes.
  Debugging: Use debugging tools to trace the execution flow and identify where the error occurs. This can help you understand the context in which the undo operation is failing.
  Consult Documentation: Review SAP documentation or community forums for any specific guidelines related to the class or object you are working with.
  
  Related Information:
