while doing confirmation trough CO11N following error comes
1) company code clearing account for 1 IN01 2 IN02 is not defined
2) company code clearing account for 1 IN02 2 IN01 is not defined
3) Posting Key is not defined
4)NO account type is specified for posting Key
If you are confirm that this order is not related to another company code then check the order thorouly, check also the operations somewhere it may be mentioned for different plant wrongly.
revert me back if not solved.
