Copy control routines in Sales Order and Debit Memo Req.

Hi,

I have a scenario wherein, I am creating a Debit Memo Request with reference to a Sales Order. DMR(Debit Memo Request ) & SO (Sales Order)will not be created on the same day. I want to have Pricing date in the DMR (both at item and Header level) as current date and dont want it to be copeid from SO.

Can it be possible with the standard available routines in copy control between SO and DMR? IS there a need for creation of separate routine.

Thanks.
