Purchase Request need to be Open when respective PO Cancelled

Hi Experts

One of my customer is asking very basic and essential requirement.

When raise the PO from Purchase Request, PR will close automatically. In the same way if you cancel the PO respective PR need to be open.

But it is not happening in SAP 9.0 PL 08

Is there any possibility to achieve this?
