Mix of CO11n and CO15

Hello,

I know its not possible to mix confírmation on Order level and Operation wise confirmation. My problem is I need to have for first and last operation the actual time/quantity. All other operation can be confirmed with planned time/quantity (for financial controlling reason)

Is it possible to confirm all operation from production order which are not confirmed yet in one step?

Is there userexit and function to confirm automatically all outstanding steps by confirmaton of the last step?

Thanks in advance,

Evgenij
