How to avoid rounding on component quantities while creating process order COR1

Hi,

We have requirement to not to make any rounding calculation on component quantity when you see on Materials tab, while creating process order.

I know there may some standard settings buy our functional guys says it impacts SD module too.

So we want to avoid that settings and explore is there any other way to just to make it work for process order creation.

We need the actual calculated quantity before rounding.

I thought of using user exit: PPCO0023 but it works only when we do some changes on the screen with components.

Thanks,

Mahesh
