  Remove References: If you determine that the field is no longer needed, you will need to:
  
  Remove the field from the data source extension or any other dependent objects.
  Ensure that any calculations, views, or reports that reference this field are updated accordingly.
  
  
  
  Delete the Field: Once all dependencies have been removed, you can proceed to delete the field &1 from the data model.
  
  
  Testing: After making changes, it is essential to test the data model to ensure that everything functions correctly without the deleted field.
  
  
  Related Information:
