Auto update values in configurable material (create sales order)

Dear Experts,

We have some scenario

In trans VA02  we add new item  with copy of existing configurable material. However , if we don’t click on configuration button before save, values in new item not update. 

I’m try to find some solution ( may be function module or class) to automatic update values when we add new item, without click on conf. icon.

Please guide us if there is any reasonable  solution
