    How to fix this error?

    Example:
    You bill an order item in an external system and transfer the billing
    document to Accounting. An error occurs when the
    <DS:GLOS.3526B886AFAB52B9E10000009B38F974>CO account assignment</> is
    determined because the order item is not yet assigned to a Controlling
    object. The error occurs either when the order item is transferred to
    Accounting, or while the transferred order item is being processed:
    Check the transfer log for the <ZH>order item</> in the external system,
    and start the transfer of the order item again.
    Then start the transfer of the <ZH>billing document</> to Accounting
    again.
