Exchange rate difference KDM in MIRO - cost center used

Question

We have recently testing to setup KDM Exchange rate difference posting in LIV and encounter the problem of cost center cannot be determine for PO with account assignment A (For asset) and P (for Project).
The question is how does the system determine the cost center for the exchange rate different account? It doesn't take the default cost center from the configuration in OKB9 but extract the cost center from PO Account Assignment - for Asset Account assignment, there is no cost center in PO and thus it is giving a error of 'Field Cost Ctr is a required field....'
Any help appreciated.

Dear Murali: Yes, GL account is maintained in OBYC for KDM transaction, I am following the OSS note 980402 for the setup (ECC6 system). The GL account say is 60000005. In OB09, we have maintained the entry for this account 60000005 to have a default cost center (e.g. 1000). This cost center does not get defaulted when MIRO posting is done with exchange rate difference. Instead, the cost center is obtained from the PO (e.g. the account assignment in PO have cost center 5000). But for certain account assignment (e.g. 'P' for WBS and 'A' for Asset), there is no cost center maintained in PO account assignment and thus in MIRO i get an error message as mentioned above.
Dear SAPFICO: check the asset master also, althrough there is a cost center in Asset Master, it does not get extracted into MIRO postings.
