Internal Order balance is Zero but still could not able to close

Hello Gurus,

We have brought the Internal Order balance to zero by means of manual FI postings. But the issue is, still we could not able to close the internal order, while closing the order we are getting error KO115 errror "Balance of ORD XXXXXXXX is not zero".

Attached the screen shot order cost analysis.

Manual posting done for the cost element 320252

Thanks & Regards

Kiran
