The remaining effort for a task can be automatically reduced based on time recorded. This is very handy if you want to burn down the remaining effort and automatically update progress or percent complete based on time recorded. We even give an option to manually edit the progress from the timesheet. It is however quite a pain if you book too much time to a task and the remaining effort is set to zero, closing the task and preventing subsequent time entry. So we have enhanced this calculation to never close the task by default, stopping the reduction in remaining effort once it reaches or goes below 10% of the original planned effort. You have the option to auto-close tasks from timesheets but it has to be configured based on the progress method assigned to your project type
