Explanation
According to the ServiceNow Hardware Asset Management documentation, the Retired state indicates that the asset is no longer in use and is ready for disposal or reuse. The substates of the Retired state are:
Disposed: The asset has been discarded or recycled.
Donated: The asset has been given away to a charity or a non-profit organization.
Vendor Credit: The asset has been returned to the vendor for a credit or a refund.
Sold: The asset has been sold to a third party.
The substate Pending Disposal is not valid for the Retired state, as it is only available for the states In Stock and In Transit. The substate Destroyed is not valid for the Retired state, as it is only available for the state In Use. References:
