When you finalize an engagement, you make its contents read-only and delete information not needed for the final engagement, such as history, notes, and workpapers. All workpapers in a finalized engagement are archived in GoFileRoom.
Engagement Manager clears the trial balance history. It clears workpaper properties specific to Engagement Manager, such as notes added, user assignments changed, signoffs added, and exports. However, the GoFileRoom history will remain, including when the document was added, edited, or archived. The history in engagement properties remains intact by design. Engagement Manager doesn't clear the document history that is stored in GoFileRoom. The engagement properties remain intentionally uncleared.
