Approval Routing feature is used to set up a hierarchy of supervisors and approvers who will approve purchase and expense transactions before they are processed.
Expense Limit – The amount the employee can expense without supervisor or approver approval.
In some cases, expense report bypasses supervisor approval. This is because if the amount is less than expense limit of the employee, then it bypasses the supervisor approval; otherwise, the supervisor approves it.
Expense Approval Limit – The maximum amount an employee can approve on an expense report when specified as an approver for another employee.
Expense limit and Expense Approval limit can be seen on the employee record’s “Human Resources” tab.
