SAP S/4HANA Error 368: Unique Constraint on Temp Table
Description
This error indicates that an attempt was made to define a unique constraint on a temporary SQL table. Temporary tables are designed for transient data within a session, and standard SQL typically prohibits unique constraints on them due to their ephemeral nature. This often occurs during custom report execution or data processing.
Error Message
ERR_SQL_TEMP_TABLE_WITH_UNIQUE: Unique constraint not allowed on temporary table
Known Causes
3 known causesIncorrect Custom SQL Definition
Custom ABAP programs or direct SQL scripts define temporary tables with an explicit `UNIQUE` constraint, which is not supported by the underlying database.
Misapplication of Table Concepts
Developers mistakenly apply permanent table design principles, such as unique constraints, to temporary tables without considering their specific limitations.
Automated Script Generation
Data migration tools or automated processes generate SQL statements that incorrectly include unique constraints on temporary tables during their operation.
