We should not use VOID on any trouble tickets – especially if the ticket you are voiding has troubleshooting notes or any information.
Even if there is another ticket already opened for the customer please just close the duplicate indicating it is a duplicate ticket and also include the other ticket number.
This way the ticket stays in the ticket history and the notes can be reviewed if necessary in the future.
If you are closing a duplicate ticket please copy the notes and paste them into the ticket you are leaving open.
Thanks.
