Std.Cost - Overhead to be calculated on % of material cost and added to the item cost during PO Rcpt

Hi All,

We have Standard costing method defined and there is a requirement where

1. Overhead cost has to be calculated on % basis of material cost and
2. it has to be added to the item cost during PO Receipt transactions and subsequently hitting the inventory valuation accounts.

we have checked the Standard Cost Absorption Rules, however we are unable to find any Percentage basis for overhead auto calculation.

Need your support.

Thanks
