External Activity Price

Dear Experts,

how to get the actual external activity price at the time of confirmation of production order.

Example : For Internal activity prices we are planning the prices in KP06/KP26 , and for actual prices we are confirming the activity time say minutes/ hrs. So we will get variances depends on confirmation.

Planning For Internal Activities KP06 /KP26
Actual Prices for Internal Activities CO11N (Plan Price* Actual qty)
Planning For External Activities CA01 Net Price directly maintained under External Processing Tab by giving a cost element Actual Price for External Activities ??????

I need to see the actual price for external activity @ PO Confirmation.....Is it possible. Plz guide me.

Thanks...
