Message No:KE249 -assign only one true cost account object

Dear All,

We have created an Production Order.

When we are doing confirmation through CO11N. In goods movement tab I am changing the stock type for GR & GI item to Q as I have done the WBS assignment in production order.

Please note we are changing the stock type of GR & GI item to Q.

System is giving error message

Enter only one true account assignment

Message no. KI249


You made assignments to several objects in CO (cost center, order, project etc.). 2 of these have been created as true objects.

System Response

You are allowed only one account assignment for each cost-relevant account.


Enter only one true account assignment.

The posting row affected is 000 and the account is 41310001.

Can body throw some light on this as we are in testing phase.

    Hi Subram,

    is the account (e.g. via OKB9 or something) linked to a cost centre.

    I assume that your production order (only) should collect the costs.

    Within transaction OMWB (account determination) you can simulate.

    Take the transactional information (e.g. movement type, material etc.) and

    simulate. The system will then present you the posting it wants to make.

    Based on that you can go further.

    If the simulation simply presents what you know already then I would

    look into OKB9 or OBBH (substitutions).

    Perhaps it helps.

    With kind regards

    • Hi,

      We have not assigned the cost element:41310001 ( COGM- Semi-finished) to any cost center in OKB9 and there is no substitution either.

      And I have checked the OMBW also in simulation ,but every thing is OK.

      What could be the reason for this error message.Please me
