Cost elements-CK11N Link

Hi,

In CK11N, we get cost by cost component sturctures. If we have cost components say Rawmateria, labor, subcontracting and if we see the cost by cost element in CK11N, we see cost of $200 for a mateial by cost element.

How and where do we define the link of that particular rawmaterial with that particulare cost element, from where does the rawmaterial picks up this cost element?

Thank you,

Nivi
