I am suggesting that you adding a way to automatically calculate the Project level finish date based on summing the durations at a task level in terms of number of days. Currently you must manually add in a start and a finish date for the project. A user experience issue came up today where we are trying to run a report to provide a list of projects based on start and finish date. If these fields are not populated at a project level then they do not show up in the project report. Also if we do manually add in a finish date at the start of the project and as the project is executed and durations change at the task level, the finish date is out of sync with the actual finish date of the project based on the due date of the last task. You must currently go in an manually update the finish date at the project level to match what is calculated as the last tasks due date based on durations and task linking.
