SAP S/4HANA Error 649: SQL Query Pinned Plan Issue
Description
Error 649, ERR_SQL_QUERY_PINNED_PLAN, indicates that the SAP HANA database cannot execute a SQL query using a previously 'pinned' or forced execution plan. This typically occurs when the optimizer determines the pinned plan is no longer valid or optimal due to underlying changes in data, schema, or system configuration, leading to a conflict with the enforced plan.
Error Message
ERR_SQL_QUERY_PINNED_PLAN
Known Causes
4 known causesOutdated Pinned Plan
A specific query execution plan was manually pinned, but subsequent changes to database statistics, data volume, or schema have rendered the pinned plan inefficient or invalid.
Schema or Data Model Changes
Significant alterations to table structures, indexes, or data distribution for the tables involved in the query have been made, which conflict with the assumptions of the pinned plan.
HANA Optimizer Inconsistency
Temporary inconsistencies or bugs in the SAP HANA database optimizer prevent it from reconciling the current query environment with the requirements of the pinned plan.
System Upgrade or Patch
A recent SAP HANA database upgrade or patch has altered the query optimizer's behavior, making a previously functional pinned plan incompatible or no longer recognized as valid.
