From Help:
Note: The Run Unrestricted option is not applied to time and expense searches by users that have roles with the Restrict Time and Expenses option enabled. Employees using a role with the Restrict Time and Expenses option enabled cannot enter expense reports or time transactions on behalf of other employees and their reports and searches do not return any time or expense transactions entered by other employees. The Restrict Time and Expenses option for a role overrides the Run Unrestricted option for a search.
