SAP S/4HANA Error 309: Correlated Subquery Syntax
Description
This error indicates an invalid SQL query structure within SAP S/4HANA, specifically when a correlated subquery attempts to use `TOP` or `ORDER BY` clauses. It typically occurs during custom report execution, data extraction, or application development involving complex SQL statements against the underlying database.
Error Message
ERR_SQL_SUBQ_TOP_ORDERBY: Correlated subquery cannot have TOP or ORDER BY
Known Causes
3 known causesIncorrect SQL Query Design
A custom SQL query, report, or application logic includes a correlated subquery that inappropriately uses `TOP` or `ORDER BY` clauses, violating database syntax rules.
Application-Generated Query Issue
In some cases, an SAP S/4HANA module or external reporting tool might generate an SQL statement containing this unsupported subquery structure.
Database Syntax Mismatch
The query might have been developed for a different database system that allows `TOP` or `ORDER BY` in correlated subqueries, but the SAP HANA database does not support this construct.
