How Do You Cancel/Void a Scheduled Payment?

 Hello All,

I have a voucher that ran through pay cycle manager, and a check was created and printed. We then canceled the checked, and a new scheduled was created on the voucher. 

The voucher is payment 2 is all "Greyed" out and we can't *Action the scheduled payment. Is there a way to cancel this voucher? I

I have tried to delete the voucher but since it has gone through processing, it's not eligible for deletion. 

How does one handle deleting a voucher that is an error?

Thanks
