COPA Planning

Dear Experts,

I created Planning level and posted sales qty and it is getting updated in Plan Column in COPA report.

But related Cost is not coming, except sales qty everything is coming Zero. I have defined Valuation stgy for Plan (point of valuation3) and defined costing key, assigned vosting key to product. Nothing is working.

Can anybody tell me details config required for that, so that i can check the missing part.

Regards,
