Task warnings indicate that you might want to take action. If inconsistencies are detected, task warnings will help you assess the situation and decide if and how you want to address them.
Warnings display
To see warnings, make sure that the "Task warnings" option is active, as indicated by a checkmark.
Warning indications will be visible directly on task cards:
and in the panel on the right under "Warnings" (in a form of a list):
Warning causes
A warning indicates one of the following:
The task period doesn't match the Box period
Assignee doesn't match the team
A given task has been assigned to a team, but the assignee is not a member of that team. 
Warning information
To see warning information pop-up, click on the exclamation point, either directly on the task card or in the sidebar on the right.
When you click on the icon, a pop-up will appear:
Locating a task on the Board
Go to the warnings list in the right-hand sidebar and click the warning icon:
- BigPicture will take you to the task
- the task is selected (highlighted in blue)
Solutions
Warnings do not have to be resolved. They inform you of certain discrepancies that you might want to fix, but if you do nothing about them, the Board module will still function without problems.
After assessing the situation, you may decide what actions are appropriate.
The task period doesn't match the Box period
If existing scheduling rules don't allow the task to be moved, using the "Align task period"/ "Re-plan for a matching Box" buttons won't work. Strong dependencies between tasks or period mode can make simplified rescheduling impossible.
The Gantt module can help you assess the situation and make necessary adjustments.
The automatic adjustment functions as follows:
- If possible, the task period won't be changed.
- If needed, the task period will be modified to fit the Box - if the task period exceeds the Box duration, the task period will be shortened to fit the Box.
- a task is moved as little as possible - it is moved only as much as needed to fit the Box.
The "Align task period" button
When you click the "Align task period" button, the task duration is modified to match the Box the task is planned for.
Case 1

The "Plan for another team" button
If the assignee is already a member of a different team, you can easily assign the task to that team.
