• What is the cause and solution for SAP error message CNV_20100164 - Op. CoA &1 missing for convers. of group CoA &2 or 'Copy Rows' is not set ?

  The SAP error message CNV_20100164 typically occurs during the conversion process in SAP, particularly when dealing with the migration of chart of accounts (CoA) data. This error indicates that there is a missing operational chart of accounts (Op. CoA) for the specified group chart of accounts (group CoA), or that the 'Copy Rows' option is not set correctly.
  Cause:
  
  Missing Operational Chart of Accounts: The operational chart of accounts that is supposed to be linked to the group chart of accounts is not defined in the system.
  Incorrect Configuration: The configuration settings for the conversion process may not be set correctly, particularly the 'Copy Rows' option, which is necessary for the data migration process.
  Data Mapping Issues: There may be issues with how the data is mapped between the group CoA and the operational CoA.
  
  Solution:
  
  
  Check Configuration:
  
  Go to the transaction code OBY6 (or the relevant configuration transaction) to check the settings for the chart of accounts.
  Ensure that the operational chart of accounts is correctly assigned to the group chart of accounts.
  
  
  
  Define Operational CoA:
  
  If the operational chart of accounts is missing, you need to create it. This can be done in the configuration settings under Financial Accounting (FI) > General Ledger Accounting > Master Data > G/L Accounts > Prepare for Migration.
  
  
  
  Set 'Copy Rows' Option:
  
  Ensure that the 'Copy Rows' option is set correctly in the conversion program or tool you are using. This may involve checking the parameters or settings in the migration tool.
  
  
  
  Review Migration Data:
  
  Check the data being migrated to ensure that it aligns with the expected structure and that all necessary mappings are in place.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation or notes related to the specific migration process you are using, as there may be additional steps or considerations specific to your version of SAP.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as OBY6, OBD2, and others related to chart of accounts configuration.
  SAP Notes: Check for any SAP Notes that may address this specific error or provide additional guidance on the conversion process.
  Migration Tools: If you are using a specific migration tool (like SAP S/4HANA Migration Cockpit), refer to its documentation for specific instructions on handling chart of accounts conversions.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or a consultant who specializes in SAP migrations.
