Which function is likely to require approval from a higher authority before proceeding?

The function that requires approval from a higher authority before proceeding is creating a purchase requisition. This process is critical as it involves initiating a purchase that commits organizational resources. Such decisions typically require oversight to ensure that the purchase aligns with budgetary constraints, procurement policies, and overall strategic goals of the organization. Approval processes are in place to prevent unauthorized expenditures and to ensure that all purchases are justified and necessary.

In contrast, viewing purchase orders is a routine task that does not usually involve higher-level authorization, as it is primarily informational. Submitting payment requests, while important, generally occurs after the purchase is already approved, focusing instead on processing payments rather than approving the initial expenditure. Changing vendor information usually involves administrative tasks that do not necessitate higher-level approval for the same reasons, such as ensuring consistency and accuracy in vendor management.
