The possible basic scenarios were checked, but none of them fits.

How to fix this error?

Check if you really do <ZH>not</> want to change the name of the CoA 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.

CNV_20100012 - Details

• The SAP error message CNV_20100012 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that a line item in a financial document does not change the Chart of Accounts (CoA), but the system has detected that the scenario being processed likely requires a change in the CoA.
  
  Cause:
  
  Inconsistent Data: The line item being processed does not align with the expected changes in the Chart of Accounts. This can happen if the data being migrated does not match the configuration or if there are discrepancies in the source data.
  
  Configuration Issues: The migration settings or mappings may not be correctly defined, leading to situations where the system expects a CoA change but does not find one.
  Business Logic: The business scenario being executed may inherently require a change in the CoA, but the specific line item does not reflect that requirement.
