Set Due Date with latest value among sub-tasks

Use case

In Jira, work can be split up into several issues. One bigger task can be split up into several sub-tasks. For keeping track of the current status, due dates can be used to indicate, when the issue should be finished. As new sub-tasks are created and the work load increases, the due date of the parent issue might not be up-to-date anymore.

In the following use case we therefore are going to set the parent issue's due date to the latest one among all sub-tasks.

🛠️ Configuration

Add the Update or copy field values post function to the create transition of the sub-tasks' workflow.
This way the due date will be automatically updated as soon as a new sub-task is created.

Target issue

Choose Parent issue

Fields

Field

Choose Due Date

Value

Choose Set field value manually

Expression

max(fieldValue({issue.dueDate},siblingSubtasks()))

By using this expression, the latest due date within all sibling sub-tasks will be grabbed.
