How To Fix CNV_20100434 - More than one country-specific CoA for CoA &1; old acct &2 not converted

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_20100 - Messageclass for chart of account conversion

• Message number: 434

• Message text: More than one country-specific CoA for CoA &1; old acct &2 not converted

What causes this issue?

Chart of accounts &V1& is the operative chart of accounts for multiple
company codes to which different country-specific charts of accounts are
assigned (&V3&, &V4& and possibly others).
Because it is not possible to determine the company code unambiguously,
it is not possible to determine the country-specific chart of accounts
either. As a consequence, the alternative account number &V2& cannot be
converted either.

How to fix this error?

Check if the alternative account number &V2& is relevant for the
conversion, and change it manually if required.

• What is the cause and solution for SAP error message CNV_20100434 - More than one country-specific CoA for CoA &1; old acct &2 not converted ?

  The SAP error message CNV_20100434 indicates that there is an issue with the conversion of the Chart of Accounts (CoA) during a data migration or conversion process. Specifically, it suggests that there are multiple country-specific Chart of Accounts defined for the specified CoA, which is causing a conflict during the conversion of the old account.
  Cause:
  
  Multiple CoAs: The primary cause of this error is that the system has identified more than one country-specific Chart of Accounts associated with the specified CoA.

  Review CoA Configuration: Check the configuration of the Chart of Accounts in the SAP system. Ensure that there is only one country-specific CoA defined for the CoA in question. You can do this by navigating to the relevant configuration settings in the SAP system.
  Adjust Mapping: If you are performing a data migration, review the mapping of the old accounts to the new Chart of Accounts. Ensure that each old account is mapped to a single new account in the target CoA.
  Consult Documentation: Refer to the SAP documentation or notes related to the specific migration or conversion process you are undertaking. There may be specific guidelines or best practices to follow.
  Use Transaction Codes: Utilize transaction codes such as OBY6 (for defining the Chart of Accounts) and OBD4 (for mapping accounts) to review and adjust the settings.
