Information

How to fix this error?

During the conversion of individual tables or table fields without
predefined derivation of organizational units, unique accounts will be
converted based on the mapping entry.
If the value also exists in non-participating chart of accounts a
warning is thrown in the log of the table
&ADDITIONAL_HINTS&
In contrary for ambigious accounts, means accounts which do exist twice
in the mapping AND with different target values the following logic
applies:
During the conversion of individual tables or table fields without
predefined derivation of organizational units, it is not possible to
correctly convert those ambigious accounts, as the related chart of
accounts can not be identified.
In these cases, the system outputs a warning message and the source
value is not converted.

• What is the cause and solution for SAP error message CNV_20100364 - More than one CoA is converted; CoA-independent mapping is unique ?

  The SAP error message CNV_20100364 typically occurs during the data conversion process in SAP, particularly when using the SAP S/4HANA Migration Cockpit or during a system conversion. This error indicates that there are multiple Chart of Accounts (CoA) entries being converted, but the mapping for the CoA-independent fields is not unique, leading to ambiguity in the conversion process.
  Cause:
  
  Multiple CoA Entries: The error arises when the system detects that more than one Chart of Accounts is being converted, but the mapping for the CoA-independent fields (like account numbers) is not clearly defined or is ambiguous.
  Non-Unique Mapping: The mapping defined for the CoA-independent fields does not uniquely identify which CoA should be used for the conversion, leading to conflicts.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review CoA Configuration:
  
  Check the configuration of the Chart of Accounts in your system. Ensure that each CoA has a unique mapping for the accounts being converted.
  
  
  
  Adjust Mapping:
  
  Go to the mapping settings in the migration cockpit or the relevant transaction where the mapping is defined. Ensure that the mapping for CoA-independent fields is unique and does not overlap with other CoA entries.
  
  
  
  Consolidate CoA:
  
  If possible, consider consolidating the CoA entries to reduce complexity. This may involve merging accounts or simplifying the structure of the CoA.
  
  
  
  Check Data Consistency:
  
  Ensure that the data being converted is consistent and does not have duplicate entries that could lead to ambiguity in the mapping.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific migration or conversion process you are undertaking. There may be specific guidelines or best practices for handling CoA conversions.
  
  
  
  Testing:
  
  After making adjustments, perform a test conversion to verify that the error has been resolved and that the mapping is functioning as expected.
