Message type: E = Error
Message class:  CNV_20100 - Messageclass for chart of account conversion 
Message number: 358
Message text: T038: GLIED=&3,ZEILT=&2,SELEK=&1: SELEK is not converted
The required organizational unit information is missing from the table
T038 for the following data record (that is, the fields BUKRS and KTOPL
are empty).
GLIED = &V3&
ZEILT = &V2&
SELEK = &V1&
Warning.
The field SELEK in the data record mentioned above is not converted.
Find out if this data record belongs to a company code or chart of
accounts that participates in the conversion.
Using the transaction CNV_PARAMS, you can specify the T038 data records
for the parameter CNV_20100_T038_SELEK_CONVERT in the table
CNV_00001_PARAMS that are meant to be converted independent of
organizational units in the cases mentioned above.
In these cases, the field CNV_00001_PARAMS-VALUEFROM must contain GLIED.
In these cases, the field CNV_00001_PARAMS-VALUETO must contain SELEK.
In these cases, the content of the field SELEK is converted independent
of organizational units (that is, in accordance with the mapping for old
and new values) in all cases for which no organizational unit is
available.
The new value for T038-SELEK would then be &V4&.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

The SAP error message CNV_20100358 T038 indicates an issue related to the conversion of a specific selection in the context of a data migration or conversion process, particularly when dealing with the T038 table, which is related to the configuration of the chart of accounts.
Cause: The error message suggests that a specific selection (SELEK) is not converted during the migration process. This can occur due to several reasons: Missing Mapping: The selection item may not have a corresponding mapping in the conversion rules. Data Inconsistency: There may be inconsistencies or missing data in the source system that prevent the conversion from being completed successfully.
Configuration Issues: The configuration settings for the migration might not be set up correctly, leading to the inability to convert certain selections. Customizations: If there are custom fields or modifications in the source system that are not accounted for in the migration process, this can lead to conversion failures.
