  The SAP error message CNV402 ("Registration for User &1 was changed") typically occurs in the context of data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that the registration status of a user has been modified, which can disrupt ongoing migration activities.
  Cause:
  
  
  User Registration Changes: The error usually arises when the registration status of a user involved in the migration process has been altered. This could happen if:

  The migration process is being executed by multiple users, and one of them has changed their registration status.
  
  
  
  Concurrency Issues: If multiple sessions or processes are trying to access or modify the same user registration data simultaneously, it can lead to inconsistencies.

  Review Logs: Check the migration logs for any additional error messages or warnings that could provide more context about the issue.
  
  
  Avoid Concurrent Access: Ensure that only one user is performing the migration tasks at a time to avoid concurrency issues.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using to see if there are any known issues or additional steps required for user registration.
  
  
  Contact SAP Support: If the issue persists after trying the above solutions, consider reaching out to SAP support for further assistance. They may provide patches or updates that address the issue.
