Posing error in QM

Hi all,

when i make an usage decision and post the material to scrap the following error is coming

Account 58015000 requires an assignment to a CO object

Message no. KI235

Diagnosis

You have not defined a CO account assignment for an account that is relevant to cost accounting

we have specified the cost center in cost element.but my client wants some alternative solution.because if i assign the cost center to the cost element all the posting to the cost element by default will go to that cost center .

pls give me an alternative solution

regards
