What is the Difference Between WBS Open/Close and Start/End dates?

Answer: The WBS Open/Close dates are visible on the admin interface in the WBS setup screen, when set the WBS record is visible on the timesheets and expense reports, but the time and expense can only be charged within the record open/close date.

The Start/End dates, if defined, will only show the WBS record during the time period between the start/end dates. The time and expenses cannot be charged retroactively after the end date has passed.
