So I've been modifying the Repair app view to suit my needs through the GUI. I've added a new char field called x_client_order_ref. 

When I finish a repair it creates a sales order, in the sales order there is already a char field called client_order_ref. 

How can I pass the value of my x_client_order_ref in the repair.order model to the corresponding sale.order model client_order_ref field? 

I'm doing all this through the GUI as I have no coding experience, can someone please walk me through this?
