Product costing report for Per UOM

Dear Experts,

I have one question to ask.

I need to calculate prodcut costing (Only for Activity type) for each produced material based on 1 quantity.

Is this achieved with OKN0 and KK01 ?( Which is explained by Ajay Maheshwari also) becoz report created in KK04 is based on total prodcued cost and produced qty.

My requirement is to Per Unit costing.

or

If I will go by Abap Development then request you to share Table or logic for the same.

regards

Sonu
