All actual hours show up in the Actual Hours column of the plan regardless of the status of the time report to which the hours belong. They do not need to be approved to show up on the plan, but rejected hours will also be displayed.
Furthermore, you can filter on what is approved or not approved in many of the standard time reports in the Analysis and Finance applications (e.g. T&E Report in Finance, Actual Hours report in Analysis, etc.).
I hope this helps!
