  Checking the migration project settings in the SAP system.
  Identifying if there are any options to reset the confirmation status.
  
  
  
  Create a New Migration Project: If resetting the settings is not possible, consider creating a new migration project. This allows you to start fresh with new settings and configurations.
  
  
  Consult Documentation: Refer to the official SAP documentation for the specific migration tool you are using. There may be specific instructions or guidelines on how to handle confirmed settings and what steps to take next.
