Updating plans

Editing the WBS display

In WBS edit, you can update a plan by editing Start date, Finish date and Duration.

Editing the Start Date

When the Start Date is edited, the Duration does not change and the Finish Date updates accordingly.

Editing the Finish Date

When the Finish Date is edited, the Start Date does not change, but the Duration either increases or decreases.

Editing the Duration

When the Duration is edited, the Start Date does not move, but the Finish Date either moves forward or back.

If you set the duration of a task as '0', it will be converted to a milestone. If you change the task duration to ‘1 day’ or more, a milestone will be converted back to a regular task.

Dragging the Gantt bar

Create a new Gantt bar

If both the start date and the finish date are not yet entered, you can create a Gantt bar by dragging using the mouse.

Editing existing Gantt bars

You can also change a plan by moving the Gantt bar, or by stretching or shortening it, using your mouse to drag the ends of the bar.


Taking holidays into account

Holidays are taken into account when a plan is changed. If only one project is displayed in WBS Gantt-Chart, and its holiday calendar is configured, the holidays are displayed with a green background. Otherwise, the holidays from the common calendar are displayed with a gray background.

Cascade Changes

If an issue's plan is postponed, the plans of any other issues which depend on this issue can also be postponed. This is done through the Cascade Changes function. 

To use Cascade Changes, you need to enable it in user preferences. For more information on user preferences, please refer to this document.


Auto-correct schedule

A child issue is a subset of a parent issue, so the plan of the parent issue includes the plan of all child issues.

When issues are edited, you can ensure that the plans of the parent and child issues are updated accordingly using the Auto-correct schedule function.

To use Auto-correct schedule, you need to enable it in user preferences. For more information on user preferences, refer to this document.

When a parent issue is moved, child issues are also moved.

Also, if planned dates are not set for a child issue,  Auto-correct schedule may not function correctly. Unless you have a specific reason for not doing so, please ensure you set planned dates.

If an issue Gantt bar is displayed with milestones, or the baseline appears as a short bar, the start and finish dates may be reversed.
Please ensure that the start date is before the finish date, or else the same as the finish date. If you update and save any other items apart from the date, these changes will not be reflected in Jira.

Switching off Auto-correct schedule

To stop Auto-correct schedule running, you need to enable an issue's Manual Mode. This allows you to set a schedule manually, so the schedule is not affected by other issues, or by the running of Auto-correct schedule.

The manual mode for versions can only be changed by the administrator.
