Hello Vincent,
The error KI230 is due to cost center accounting is
not activated in OKKP. It means system is not ready for anyone to use
cost centers in controlling area HNPF.
You would need to resolve this error by transaction code OKKP, choose
controlling area HNPF, activate cost center accounting in fiscal year
2013 to allow you can use this cost center in 2013.
Hope this helps.
Best regards,
Jasmine
