  If a Web visual component exists for the field to be deleted, a warning message will be displayed. If the field is deleted, the web details will also be deleted.
  It should be noted that there are many reasons for a delete operation to be refused. For example, the field is used in a file definition, other fields refer to this field and so on. In all cases the message issued will describe the reasons for the delete request to be rejected.
