Update progress for the project

Choose Tools, Apply Actuals.
Make sure the projects you want to update appear in the Project(s) to be Updated list.
Specify whether to use the data date for each project, or assign a new data date to all the projects you are updating.
In the New Data Date field, specify a new data date for the projects, then click Apply.
Choose Project, Activities, then select the activity you want to update.
Display Activity Details, then click the Status tab.
Mark the Started checkbox to indicate that the activity started early or mark the Finished checkbox to indicate that the activity completed early.

If the activity was supposed to start during the update period but did not, clear the Started checkbox.

If the activity was supposed to finish during the update period but did not, clear the Finished checkbox.
In Activity Details, adjust any activity information, such as Expected Finish or Remaining Duration, that did not progress according to plan.

When you add an Expected Finish date, the calendar defaults to the date and time of the activity's Early Finish date.

When you edit an Expected Finish date, the calendar defaults to the date and time that is currently in the Exp Finish field.
