Logging time against a task is easy in PlanRight. Enter the amount of time worked into the Log Time field and click Save. This will deduct the entered time from the total estimated effort and update the number of hours remaining on the task. It will also create a timesheet which can be viewed on the Timesheets page in the menu, and adds a timesheet for the task in WFM/XPM as well. For Admins, this page can be found under the Reporting menu item.
Editing the Estimated Hrs Remaining is a manual way of recording how much time you estimate the task will take. This is a great way to communicate that the time it will take for the task to be completed may be different to the Allocated Hrs Remaining. For example if you have 1 hour of Allocated Hrs Remaining, but an Estimated Hrs Remaining of 3, This would indicate that the task is going to go over budget by 2 hours. In reverse you may have 5 hrs allocated, but it may only take 2 hrs, so you would have an Estimated Hrs Remaining of 2.
Estimate Hrs Remaining is not synced to WFM and does not apply to other instances of the task.
