SAP S/4HANA Error 306: Invalid SQL Cursor Operation
Description
This error indicates an attempt to use an SQL cursor that is not in a valid state. This can occur when an application tries to fetch data from a closed cursor, an unopened cursor, or one that has become invalid due to session termination or resource issues. It typically points to a programmatic issue within a custom report, interface, or database procedure interacting with SAP S/4HANA's underlying database.
