SAP S/4HANA Error 496: Table Already Non-Extended
Description
This error occurs when an operation attempts to convert a database table from an 'extended' to a 'non-extended' format, but the table is already configured as non-extended. It typically indicates a redundant or unnecessary conversion attempt during database management, system upgrades, or custom development processes.
Error Message
ERROR_SQL_INVALID_CONV_FROM_EXTENDED
Known Causes
3 known causesRedundant Conversion Attempt
An explicit database operation or system process tried to change a table's extension status, but the table was already in the desired non-extended state.
Flawed Program Logic
Custom scripts, migration tools, or application logic incorrectly initiated a conversion for a table that did not require it, based on its current configuration.
Metadata Desynchronization
A discrepancy between the system's recorded table properties and the actual database state led to an attempt to perform an already completed or unnecessary conversion.
