SAP S/4HANA Error 400: Primary Key Conflict
Description
This error indicates an attempt to define or modify a database table within SAP S/4HANA with both a primary key constraint and an 'insert-only' property. These two properties are mutually exclusive, as primary keys imply updatability and uniqueness enforcement beyond simple insertion.
Error Message
ERR_SQL_INSERT_ONLY_TABLE_WITH_PRIMARY_KEY
Known Causes
3 known causesIncorrect Table Definition
The table was initially created or customized with conflicting properties, specifying both a primary key and an insert-only flag.
Accidental Primary Key Addition
A primary key constraint was inadvertently added to an existing table that was designed or intended to be insert-only, such as a log or historical data table.
Misunderstanding of Table Types
Developers or administrators may not have fully understood the implications of 'insert-only' tables, which are typically append-only and do not support primary key constraints.
