  Refresh the Data: 
  
  Close the current transaction and reopen the BOM. This will fetch the latest version of the BOM from the database.
  
  
  
  Save Your Changes:

  Check for Changes:
  
  After refreshing, review the BOM to see what changes have been made. You may need to reapply your changes based on the new data.
  
  
  
  Communicate with Other Users:
