Auto selection of Serial Numbers in Va02

Hi Experts,

I have one problem, When i m doing delivery creation using my Outbound delivery no created for one of my serialized product then when i select my item and click on serial numbers option from menu and after entering delivery no. i am shown list of serilal numbers bound to be delivered. The my problem is when i select copy button to select all the selected serial numbers as shown in list, no data is copied. And because of this i had to mannually copy all those serial numbers screen by screen using Ctrl + Y to select all the serial numbers. When i have to process huge order it becomes cumbersome activy so i request u to please provide solution to this proble that why is not all my serial numbers are being copied through the list at once automatically upon giving the delivery no and on using the copying tool?

Thanks
