• What is the cause and solution for SAP error message CNV20600064 - Target company code & exists already; no 1:1 rename! ?

  The SAP error message CNV20600064 indicates that there is an issue with the target company code during a data migration or conversion process. Specifically, the error states that the target company code already exists in the system, and therefore, a 1:1 rename (which would typically involve renaming or mapping one company code to another) cannot be performed.
  Cause:
  
  Existing Company Code: The target company code you are trying to create or rename already exists in the SAP system.
  Data Migration Conflicts: During data migration, if the target company code is already in use, the system will not allow the operation to proceed to avoid data integrity issues.
  Configuration Issues: There may be configuration settings or migration settings that are not aligned with the intended operation.
  
  Solution:
  
  
  Check Existing Company Codes: Verify the list of existing company codes in your SAP system. You can do this by navigating to the relevant transaction (e.g., OX02 for company code configuration) and checking if the target company code is already present.
  
  
  Rename or Delete Existing Company Code: If the existing company code is not needed, you may consider renaming or deleting it. However, be cautious with this approach as it may have implications on existing data and configurations.
  
  
  Use a Different Target Company Code: If the existing company code is required, consider using a different target company code for your migration or conversion process.
  
  
  Review Migration Settings: Check the settings in your migration tool or program to ensure that they are correctly configured to handle existing company codes. This may involve adjusting mapping settings or ensuring that the migration logic accommodates existing entries.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration or conversion process you are using. There may be specific guidelines or best practices for handling existing company codes.
  
  
  Seek Support: If you are unable to resolve the issue, consider reaching out to SAP support or consulting with an SAP expert who can provide guidance based on your specific scenario.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as OX02 (for company code configuration) and others related to your migration process.
  SAP Notes: Search for SAP Notes related to the CNV20600064 error for any patches or updates that may address the issue.
  Data Migration Tools: If you are using specific data migration tools (like SAP S/4HANA Migration Cockpit or SAP Data Services), review their documentation for handling existing records.
