Reallocation of a task invokes the task's initial allocation strategy. This results in the task being reassigned to the item (group of users or work queue) to which it was originally assigned by the system. It should be noted that this is a different action from un-reserving a task. Unreserving a task assigns the task to the last group it was assigned to before being reserved. Reallocating a task uses the initial task allocation strategy, which will usually assign the task to the first group it was assigned to, if no changes have been made to the allocation strategy or groups in the mean time.
