The current asset attached to a ticket is visible on the right side of a ticket’s details page. You can change an asset on a ticket by using the Options drop-down menu. From here you can Change Device to change the asset to a different hardware device. Or you change to a different asset type (Software/Online Systems, Other Request, User Account, Network/Wifi).
If an asset is missing important information, like an asset tag, that asset will need to be verified before the ticket can be completed. (Note: this action only needs to be done once per device)
