Some times you have items which come back iteration after iteration. In Planbox you can do that by making an item recurring. To do so, click on Add Recurrence. You can turn off recurrence by pressing on the link in the same location again.

Recurring items are special. When the Current iteration ends (move to history), any item marked recurring will be duplicated in the new Current iteration. Its tasks are reset. Any attached files and written comments remain.

NOTE: Recurring items only make sense in the Current iteration. They can exist in Future iterations and the Backlog. However they will not be duplicated in a move to history.
