Hi Thannapong.
Why don't you use 1 Automatic Final confirmation? It will work as 'final confirmation' and partial confirmation as per the confirmation yield. Also user has option to change the confirmation type in COR6N.
If you want by default then please use the BAdi WORKORDER_CONFIRM I have suggested in my previous posting or Enhancement like CONFPP02 PP order conf.: Customer specific input checks or CONFPP06 PP Order Confirmations: Actual Data Transfer
I hope it will work for you.
