  Adjusting the opening date to an earlier date.
  Changing the closure date to a later date if the account is still active.
  
  
  Data Validation: Ensure that any data entry or import processes that populate these dates are validated to prevent similar issues in the future.
  Consult Documentation: If you are unsure how to make these changes, refer to your organization's SAP documentation or consult with your SAP administrator or support team.
