  Solution:
  
  Refresh the Data: Before making any changes, refresh the business partner data to ensure you have the latest version. You can do this by reloading the business partner details.
  Check for Changes: If you receive the error, check if another user has made changes. You may need to communicate with your team to understand what changes were made.
