Hi Declan,
Thank you for your kindly reply.
I checked OKOA, the description of CF type is "G/L account document".
Since the function area of the order and the cost center are different, order to cost center also generate FI document. So I think it should use SU type which defined in settlement profile. Another question, if order to cost center is internal settlement, which type it should use? Is this a default configuration?
Looking forward to your reply.
Thank you!
