The Update Tasks page enables you to select and simultaneously delete multiple unpublished tasks.

If you have enabled workplan versioning and have created multiple versions of your workplan, several versions of the same task may exist. If you select one of these task versions for deletion the system only deletes that task version.

If you have enabled workplan versioning and published workplan versions contain the task you have selected for deletion, the system will not delete the selected task until you publish the task's workplan version. Tasks "waiting for deletion" are marked with a blue circle next to their outline number.

You cannot delete tasks in published workplan versions.

When cost breakdown planning is enabled for a project and a task in the workplan is deleted, the associated cost codes are also deleted. You can remove cost codes that are enabled or disabled in the cost breakdown structure or copied from other tasks or a workplan. You can also remove cost codes if the parent cost codes or the child cost codes are not removed. However, you cannot delete cost codes if they are used in resource assignment or referenced in an actual transaction for the task. When you remove a cost code it cannot be used in any source transaction or expenditure item. You can change the cost code associated to an actual expenditure item but the changed cost code cannot be mapped to the original cost code
