Which of the following is not a Cancel Reason option?

The choice indicating "Cancelled by Administrator" is not a Cancel Reason option, as the function typically reflects actions taken by individuals or systems directly associated with the employees or the functioning of the software rather than an administrative action. In most systems, cancel reasons are categorized under individual actions such as an employee or a supervisor taking steps to cancel a process.

In contrast, the categories involving "Cancelled by Employee," "Cancelled by Supervisor," and "Cancelled by System" demonstrate specific roles or automated processes that directly relate to the handling of cancellations. These reflect an understanding of who or what initiates the cancellation, making them valid options in the context of tracking and managing cancellations. Hence, since administrative actions typically fall outside of the direct user interactivity that the other reasons imply, it clarifies why this particular choice is not included in the standard options for cancel reasons.
