You can unlink a Child trouble ticket from its Parent trouble ticket. This is accomplished from either the Edit Trouble Ticket or View Trouble Ticket window.
To unlink a Child trouble ticket from its Parent trouble ticket:
Click the Journals tab in the Customer window.
Right-click on the Child trouble ticket, and select View (if Child trouble ticket is closed) or Edit (if Child trouble ticket is open).
From the View Trouble Ticket or Edit Trouble Ticket window, click the Actions button in the bottom left-hand corner of the window, and select Unlink Parent Trouble.
This unlinks the Child trouble ticket from its Parent trouble ticket and converts it back to a basic trouble ticket (not a Child or a Parent). The Parent Trouble field is cleared in the Edit/View Trouble Ticket window.
Click Save to close the Edit/View Trouble Ticket window and remove the Child status from the trouble ticket.
