  Change the transportation zone for these customers to another valid zone.
  Delete the customer assignments to the transportation zone if they are no longer needed.
  
  
  
  
  
  Check Related Master Data:
  
  Ensure that there are no other master data objects (like shipping points, plants, etc.) that are still linked to the transportation zone.
  
  
  
  Retry the Operation:
  
  After making the necessary changes, attempt to delete or modify the transportation zone again.
  
  
  
  Related Information:
  
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as:
