How to fix this error?

Find out if you really want to change accounts, and if the <ZK>Copy Rows
</> indicator is set correctly.
If the <ZK>Copy Rows</> indicator is set, the master data of old CoA X
is copied to Y when CoA X is converted into Y (and, if necessary,
accounts are merged or renamed), while old CoA X will still exist
without any changes after the conversion.
