Inconsistency in classification data ==> transaction terminated

HI All,

When user tried confirming a process order via t-code CORK, the message :"Inconsistency in classification data ==> transaction terminated" appeared.

While reading the forums, it was suggested that I run t-code BMCC to fix the inconsistencies in the batch. After that, user tried confirmation again, the error is still there.

How do I fix this error, if BMCC doesn't work?

Thanks!
