% Complete - Date Achieved % Complete - Date Achieved Northgd (TechnicalUser) (OP) 27 Feb 14 06:15 Hopefully this will ba nice easy one I need to set overall project completion to a percentage, I then need the date when this will be achieved (theroetical) Is there a simple way to achieve this ? Many thanks Dave RE: % Complete - Date Achieved SkipVought (Programmer) 27 Feb 14 10:04 hi, Pct * ([Scheduled Project Finish] - [Scheduled Project Start]) + [Scheduled Project Start] or [Scheduled Project Start] * (Pct * ([Scheduled Project Finish] - 1) + 1) Assuming the project actually started on the scheduled start date, otherwise you must shift the projected end date accordingly. Skip, Just traded in my OLD subtlety... for a NUance! RE: % Complete - Date Achieved Northgd (TechnicalUser) (OP) 27 Feb 14 11:44 Thanks. D RE: % Complete - Date Achieved JulieInMaine (TechnicalUser) 27 Feb 14 15:39 You can use the update project command to update a series of tasks (or all tasks) as of a specific date. As Skip notes, % complete is a duration measurement in Project. It is calculated as [Actual Duration]/[duration]*100. RE: % Complete - Date Achieved remeng (TechnicalUser) 28 Feb 14 11:37 You can always use the summary task and the project % complete will automatically be calculated for you without having to create code.
