Task Actual Start Date Auto-Population Type

All tasks in PI have an Actual Start and End Date, which reflects when the Task's work actually took place rather than when it was planned. Either the Task Owner or PM has access to this data, depending on how you have your settings enabled in the Default Task Options. 

• The PM or task owner can also restrict those changes with "...No Editing Allowed." At that point the Actual Start Date cannot be changed

• No Auto Population will require that the actual start date is filled in manually. Otherwise, the actual start date remain null/blank.
• Scheduled Date will change the actual start date/time to match the scheduled start date/time as soon as the percent complete for the task is changed to something other than 0% complete.
• % Complete Updated Date will change the actual start date to match the date that the task is changed from a percent complete of 0% to a percent complete of greater than 0%. The start time will be set to be the same as what is set in the task's work calendar start time for that day.
• % Complete Updated Date, No Editing Allowed is the same as above without an option to change the date/time with a manual entry override.
• % Complete Updated Date & Time will change the actual start date and time to match the date and time that the task is changed from a percent complete of 0% to a percent complete of greater than 0%.
• % Complete Updated Date & Time, No Editing Allowed is the same as above without an option to change the date/time with a manual entry override.
• Time Entry Date, when Updated will update the actual start date/time to match the date/time of the earliest time entry in the task.
• Time Entry Date, when Updated, No Editing Allowed is the same as above without an option to change the date/time with a manual entry override.

If one of the % Complete options are used and a task is marked to 100% complete, the actual start date will be automatically entered, but if the percent complete is then changed back to something other than 100%, the actual start date will be removed.
