Error message in down payment on asset purchase order

Question

Hello,,
While i am trying to make down payment request with reference to PO have asset number it is return an error message
*Store a cost element for credit down payments
    Message no. KI165
Diagnosis
    You posted a payment to a CO-relevant object (cost center, order, and so
    on). The payment is therefore recorded in CO.
    If a payment has no order reference, no consumption account can be
    derived. Therefore, CO posts the payment under a default cost element
    created and stored during Customizing.
    You have not yet maintained this default in the system.
Procedure
    Maintain the default cost and revenue elements in the Implementation
    Guide under "Project System" for controlling area CA00.*
I don`t know what is the reason for using this cost element and which type of cost elements that i can use in this issue....
We are not use Down payment clearing account, because Our customer don`t need this account..
Please help me ASAP
Thanks for your cooperation
Hussein

Hello Hussein,
For error message KI165,please maintanin default cost  element in OKEP.Down payments have to be posted in CO with cost   elements. In case of purchase orders (or open items in CO), the cost  element for consumption can be derived from the purchase order. Thus the  down payment in CO is posted with the consumption cost element.                                                                               
If the  down payment does not have any reference to a purchase order, then the cost element for which the consumption will be posted is not known.  In this case, the cost element maintained with OKEP is used.                     
The error message KI165 will occur if no cost element is maintained with  OKEP - not regarding whether the actual down payment has a reference to  a purchase order and thus will update in CO under the consumption cost element derived from the purchase order.  This is always a  source of  misunderstanding - but I hope it is clear now.                                                                               
OKEP configuration is absolutely necessary if you do not have  a cost element assigned at the time of downpayment request creation.                                                                               
If after maintaining the default cost element you get some other error  then please note that you would need to check the following :                                                                               
1.Compare the configuration settings for the GL accounts that are  used for posting the cash call in EHP4 system with the system without the EHP4 support pack.               
2.Check the controlling area settings in both the systems.
