Structure.Gantt highlights any scheduling conflicts with a dark red line placed on top of the task bar. To review and resolve the conflict, open the Task Details panel. The conflict will be explained at the bottom of the panel, along with resolution options.

Dependency-based Scheduling Conflicts

Issue dependencies may create conflicts when manual scheduling is enabled. For example, for finish-to-start dependencies, if a task is scheduled for a date earlier than its predecessor's Finish Date, Structure.Gantt will highlight this conflict.

Scheduling conflict caused by task links


To deal with the conflict, click the task and select one of the following actions:

When sprint-based scheduling is used, dependent issues in the same sprint will not be marked as a conflict, since they can be completed at any point during the sprint.


If Resource Leveling is active, any leveling delays affecting the item will be removed when Respect Link or Auto Schedule is selected.


Duration/Work Estimate Conflicts

If a task is scheduled for a fixed duration shorter than its work estimate, you will receive an error message.

Scheduling conflict caused by fixed task duration


When this occurs, you have a few options to resolve the conflict:

If Prefer sprints over manual start and finish dates is selected in your Gantt configuration, the Increase Duration option will be unavailable, because changing the start date would have no effect when sprints take precedence.
