Period warnings

Period warnings occur when a parent task can not be recalculated due to a constraint, such as a blocking task (for example, a task in Locked mode), non-working day, or when you use the manual period mode.

Showing Period Warnings

The warning is displayed as a yellow box with a dashed-line frame and shows the position of the parent tasks calculated based on its children.

Period warnings do NOT consider tasks without start and end dates (tasks without dates are ignored by period warnings).

Period warning considers tasks with one date, only considering the existing date.
