Hello Maitre

while there is no pre-configured work packages view that shows only work packages with the status "finished", you can easily create such view for yourself (private) or others in your organization (public). To do so, first configure the work package table as desired (e.g. filter for status = finished) and then save this view with an appropriate name. The saved view will appear next to the default ones at the sidebar.

There is also a step-by-step guide which should provide more information on this topic.
