• What is the cause and solution for SAP error message CD789 - Class & was created/overwritten ?

  The SAP error message CD789 typically indicates that a class was created or overwritten in the system. This message is often related to the Object-Oriented Programming (OOP) features in SAP, particularly when dealing with ABAP classes.
  Cause:
  
  
  Class Creation/Modification: The error usually occurs when a class is being created or modified in the ABAP Workbench (transaction SE80 or SE24). This can happen if:
  
  A developer is trying to create a new class with the same name as an existing class.
  An existing class is being modified, and the system is warning that it will overwrite the previous version.
  
  
  
  Transport Issues: If the class is part of a transport request and there are inconsistencies in the transport directory, it may lead to this error.
  
  
  Authorization Issues: The user may not have the necessary authorizations to create or modify classes, leading to warnings or errors.
  
  
  Solution:
  
  
  Check Class Name: Ensure that the class name you are trying to create does not already exist. If it does, consider using a different name or modifying the existing class instead.
  
  
  Review Changes: If you are modifying an existing class, review the changes you are making. Ensure that you are aware of the implications of overwriting the class.
  
  
  Transport Management: If the issue is related to transport requests, check the transport logs and ensure that all transports are correctly imported and that there are no inconsistencies.
  
  
  Authorization Check: Verify that you have the necessary authorizations to create or modify classes. You may need to contact your SAP security team to ensure your user role has the appropriate permissions.
  
  
  Backup: If you are overwriting an existing class, consider backing up the current version of the class before making changes. This can help you restore it if needed.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SE80 (Object Navigator) and SE24 (Class Builder) for managing classes.
  Documentation: Review SAP documentation on ABAP classes and object-oriented programming to understand best practices and guidelines.
  SAP Notes: Check SAP Notes for any known issues or patches related to class management and error messages.
  
  If the problem persists after following these steps, consider reaching out to your SAP Basis or development team for further assistance.
