Quantity-Based OH Rate with KM<>KG conversion for each FG (using userexit)

Hi,

My requirement is:

I want to add quantity based overhead to finished products which has Base Unit of Measure as u201CKMu201D whereas Overhead rate is applicable per u201CKGu201D of finished product. I have the "KM" <--->"KG" conversion for each finished product which can be maintained in the material master-> additional data. Now I do not know how to use conversion from Base Unit of Measure in cost sheet.

In this given scenario, what additional steps or pre-requisite have to be done. what is the suitable user-exit available (e.g. Exit_SAPLKASC_001, Exit_SAPLKASC_002 and Exit_SAPLKASC_003)? If anyone had faced similar issue, please guide the logical way to achieve this.

Thanking you.
