Reverse FI Invoice & Clear

Hi,

Need to have FI reverse invoice and also have it cleared. The goods have not been delivered to the customer.

I need to have the invoice cleared, canceled, reverse the goods issue, cancel the delivery, and close the sales order?

Do i use FB08 to reverse the document, but would this clear the document at the same time? But how do undo the rest of the items? Is there a one step process or several steps? Can someone please explain this to me.

Thanks
