P4210 - cost should be overridden/replaced by actual selling price

Hello,

I am looking for a set up  in P4210 application

Whenever an order is entered using this application,

We enter customer details, Branch plant, quantity and item.

System automatically populates unit cost UNCS & unit price PRRC and we save the order – Standard process.

Requirement – I need to populate PRRC value in UNCS field in the order & PRRC field value will be zero( cost should be overridden/replaced  by actual selling price)

                         Whatever is the unit price in the order should be stored in unit cost field (UNCS)

Let me know if we get something on this.

Thanks
