  Creating a new destination SU.
  Adjusting the transfer order to reflect the correct SUs.
  
  
  
  Review the Transfer Order: If you are working with a transfer order, check the details of the order to ensure that the source and destination SUs are set up correctly.
  
  
  Consult Documentation: If you are unsure about the process, refer to your organization's SAP documentation or consult with your SAP support team for guidance on handling stock transfers.
