Message type: E = Error
Message class:  CNV_20100 - Messageclass for chart of account conversion 
Message number: 354
Message text: Org.indep. conv. with unique target values for &1. Field is converted.
The conversion for this table/field is done independent of the
organizational unit, hence no chart of accounts information is available
There is exactly one target value for the source value &V1& in the
mapping for G/L accounts or cost elements
Nevertheless the value &V1& does also exist in non-participating chart
of accounts
Due to the fact that the conversion is done independent of
organizational units it is assumed that the value &V1& belongs to the
chart of accounts specified in the mapping for this value.
The affected value &V1& is converted to &V2& independent of
organizational units.
Check if this table is converted correctly.
If no, specify a proper determination path for org. units for affected
fields.

The SAP error message CNV_20100354 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data conversion tools. This error indicates that there is an issue with the conversion of organizational independent data, specifically that the target values for a certain field are expected to be unique, but they are not.
Cause: The error message suggests that the system has encountered a situation where the source data contains multiple entries that map to the same target value for the specified field. This can happen due to: Duplicate Entries: The source data may have duplicate entries for the organizational unit or other relevant fields that are supposed to be unique in the target system. Mapping Issues: The mapping configuration may not be set up correctly, leading to conflicts in how source values are translated to target values. Data Quality Issues: The source data may have inconsistencies or errors
