When you complete a Task, the system will check to see if you have elected to make it a recurring item by selecting the Recurring Option. If you have made the Task a recurring Task, the current Task is completed as normal and a new, identical Task is created.
We do this so that your productivity levels are more accurate when viewing the dashboard or producing a report of completed Tasks, while at the same time creating the Task for next time so that you don't forget to add it again.
This is particularly useful for periodic Tasks such as completing Monthly Business Expenses etc.
