We are performing an upgrade from ECC5 to ECC6 (enhancement pk 6). We are getting a common error with FI postings for inventory movements in MM. We get the error KI235 - Account xxxxxx requires an assignment to a CO object.
I think to fix the problem is fairly straightforward, but what is puzzling us is why we are getting the error in ECC6 when we did not receive the error in ECC5. What standard functionality changed to cause the error?
