Update Selected Tasks in Project
When you click Update in the Task List page for a project, WorldServer schedules for update all tasks selected in the update view.
When you click Update, the Update Tasks confirmation dialog box displays; if you click OK, all selected tasks are put into a
Pending Update state. Select Include in project cost calculation if you want all the work that has occurred in the tasks to be updated in the project cost calculation.
The tasks pending update are updated (that is, canceled and restarted) when a workflow step that allows for task update has been completed.
