Dialog box location
Display any task view. On the Tools menu, point to Tracking, and then click Update Project.
Update work as complete through section
Update work as complete through Select to update the work that has actually occurred, according to how the project was scheduled. Enter the date you're updating the schedule to. With this option, Microsoft Office Project treats your scheduled dates as actual dates and sets the % Complete field to reflect this. The date you enter becomes the status date for the project.
For the selected tasks, the scheduled start and finish dates are compared with the date you're updating the schedule to.
If the scheduled start date is after the date you enter in this dialog box, the task is considered not started, and it is set to 0% complete.
If the scheduled finish date is before the date you enter, the task is considered completed, and it is set to 100% complete.
If the scheduled start date is before the date you enter and the scheduled finish date is after the date you enter, the task is considered in progress. Project calculates the percentage of completion.
When you update task dates, Project updates the % Complete field. You can have Project calculate the approximate percentage of the task that has been completed as of the date you enter in this dialog box. Alternatively, you can have it leave the percentage of completion set to zero if the task is in progress or set it to 100 if the task is complete. Project also sets the actual start date, which indicates that the task is in progress.
Set 0% - 100% complete Select to set the percent complete within a range of 0 to 100, based on the date in the Update work as complete through box. Tasks that have not started are set to 0. Tasks that have been completed are set to 100. If a task is in progress, Project calculates the percentage that has been completed and sets the percent complete to that value.
Set 0% or 100% complete only Select to set tasks that are scheduled to finish by the "complete through" date to 100% complete. The percentage complete value for tasks that will not finish by the "complete through" date does not change.
Reschedule uncompleted work to start after section
Reschedule uncompleted work to start after Select to have Microsoft Office Project reschedule all uncompleted work to begin on the new start date that you enter in the date box.
If a task has not started by the specified date, the task has slipped. Project reschedules the work, setting the scheduled start date to your specified date and applying the Start No Earlier Than (SNET) constraint.
If the task is in progress but behind schedule, Project schedules the remaining duration to start on your specified date.
When you reschedule tasks with this option, Project sets the Stop and Resume fields. The date of last reported progress is placed into the Stop field, and your specified date for rescheduling is placed in the Resume field.
You can specify whether to allow in-progress tasks to be split. On the Tools menu, click Options, and then click the Schedule tab. Be sure that the Split in-progress tasks check box is selected. This allows Project to reschedule uncompleted work with the Update Project dialog box. The Split in-progress tasks check box is selected by default.
Entire project Select to set actual work information for all tasks in the project.
Selected tasks Select to set actual work information for the selected tasks only.
Use the Update Project dialog box to generally track and update groups of tasks. The options in this dialog box are most useful if you want to track tasks but don't need to do so in detail. If you need to track tasks in detail, use the Update Tasks dialog box.
You can use the Tracking toolbar to quickly update actuals. On the View menu, point to Toolbars, and then click Tracking. Select tasks and then click the button for the tasks' percentage of completion.
