Hansoft offers functionality to link a task/item/bug to another task/item/bug. One of the most common scenarios is to link bugs to tasks and vice versa. This is useful, for example, when there are bugs related to a new feature in the product or in similar scenarios.
To activate this function, you must activate the extra column "Linked to task/item/bug" in Customize project (both in QA and in the Planning section):
Go to the task or backlog item and select Link to tasks, items or bugs:
Now go to the QA view, right click and select Link to selected:
A link to the task/backlog item will now be visible in the column (it is cross-linked so a bug link is visible in the Planning section):
