Each warning is explained with its purpose, when it appears, and how users can resolve or respond to it.

### [Overdue tasks](https://appfire.atlassian.net/wiki/spaces/DLP/pages/2211190043)

Overdue tasks are all those that have been due in the past but whose progress status is currently below 100% and/or whose status is still **To do** or **In progress**.

### [Period warnings](https://appfire.atlassian.net/wiki/spaces/DLP/pages/2212496263)

Period warnings appear when a parent task can not be recalculated due to a constraint, such as a blocking task resulting from the scheduling mode.

### [Dependency loops](https://appfire.atlassian.net/wiki/spaces/DLP/pages/2211745955)

If you add predecessor relationships between tasks, you might encounter a dependency loop. This happens when two or more tasks depend on each other. BigPicture prevents you from creating these loops to keep your task flow working properly.
