Zero-duration Tasks

Gantt Charts for Structure supports tasks with zero duration, based on the following:

• The Duration field in the Task Details panel is set to '0'

• The Duration attribute has a value of '0'

• A '0' is entered as the issue's time estimate value (note: if the estimate is blank, the default estimate will be used).

When a task has a duration of zero:

• It will appear on the timeline as a narrow task bar

• It will not affect resource allocation, even if it is assigned to a resource

Notice that all the issues are assigned to the same resource, but only BP-1 affects that resource's allocation. The other tasks all have zero duration.
