Message number: 213
Message text: Set data must be transferred into transparent tables
In Release 3.x, the sets were stored in tables T800S, T800X, T800Y and
SETDATA.
From SAP release 4.0 onwards, sets are stored in transparent tables.
The sets that were created under Release 3.x were not transferred during
the put from Release 3.x to 4.x, that is, they were left in the old
tables.
Set data in tables T800S, T800X, T800Y and SETDATA cannot be considered
and converted by the chart of accounts conversion tool.
You must transfer these set data into the correct tables before the
conversion.
For Release 4.0B start programs RGSOLD2N and RGSOLDDL.
For Release 4.5 and higher start program RGX_SETS_TO_40.
Having completed the transfer of the old set data, re-execute activity

Error message extract from SAP system. Copyright SAP SE.
The SAP error message CNV_20100213 indicates that there is an issue with the data transfer process, specifically that the set data must be transferred into transparent tables. This error typically arises during data migration or conversion processes, particularly when using SAP's data migration tools.
Cause: Data Structure Mismatch: The error often occurs when the data being transferred is not compatible with the target table structure. This can happen if the source data is in a format that does not align with the transparent tables in the SAP system. Use of Non-Transparent Tables: The data might be attempting to be transferred into a non-transparent table (like a pooled or cluster table), which is not allowed for certain operations.
Configuration Issues: There may be configuration settings in the data migration tool that are not set correctly, leading to this error.
Solution: Check Data Mapping: Ensure that the data being transferred is correctly mapped to the target transparent tables.
