Duplicate Recordset of 2 tables

[k0023382]

Hi all,
This is the challenge.
I take as example the NorthWind database coming with Access.
I want to add a button on the Orden form that allow me to add a new order
exactly the same as the current order (including orderdetails records).

Sometimes the customer order exactly the same that last time, so on this
situation such funcionality will be great.

How on earth can I do this?
What code do I need behind this button?

Thanks a lot
Francisco
