If the workflow allows, you can reject a task. When you do, the task goes to another step as defined in the template. If the task is directed to a group of users, it is deleted from your Inbox. Whether the task remains in the Inboxes of the other users in the group depends on the template definition.
To reject a task:
In your Inbox, open the task by clicking its name.
Click Reject.
If required, type a message explaining the reason for the rejection.
Click Next.
To select other tasks to reject, do so from the Select Next Reject Tasks list.
If required, type your password in the Sign Off Required field to electronically sign off the task.
Click OK.
