Depreceation posting

Hi all

while running the depreceation run. error is coming as " assing a co object for the account XXXX(which is a Dep account)". my doubt is we are assigning the cost center for each asset in the master data. while calculation the depreceation will the system pick this cost center?.if not where shall i give this assignment.

deprecetion should be posted to the cost center in which the asset is belonging.

how to do this ?

thanks
