When updating progress for a project, you might need to record that the work on a particular activity has been suspended or resumed after a period of inactivity. For example, an activity might be suspended or resumed due to a plant shutdown. To record this, you must enter suspend and resume dates. The suspend date is the date on which an activity's progress has, or is planned to be, stopped. The resume date is the date progress on an activity begins again. When you indicate a suspend or resume date, work for the activity is considered to be suspended or resumed at the beginning of the specified day.
