Revert/reverse approval is currently only available for engineering requisitions.
If you want to revert the approval back to a previous approver, type a comment in the Approver Comment box, and click Revert. A dialog opens.
Select the approver to whom the approval sequence should revert, and click Revert. The approval cycle will start again from the selected user who will receive an email with an invitation to approve once again.
If you want to reverse the entire approval sequence, click Reverse Approval. Emails will be sent to the approvers stating that the approval cycle is reversed.
