SAP Errors Catalog Part 2: BASIS Administration, System Logs & HANA DB Errors

SAP Errors Catalog - Part 2: BASIS Administration & HANA DB

Comprehensive guide to work process bottlenecks (SM50/SM66), memory heap limits, Enqueue lock table overflows (SM12), system log alerts (SM21), and SAP HANA database memory faults (ST04/DB02).

1. Work Process & Execution Timeout Errors

TIMEOUT

TIME_OUT (Maximum Run Time Exceeded)

A dialog work process exceeded the maximum allowed continuous execution time limit (defined by profile parameter rdisp/max_wprun_time).

Resolution

Schedule long-running reports as background jobs (Batch/Background Work Process), or temporarily adjust rdisp/max_wprun_time in RZ11.

WORK PROCESS

Work Process in PRIV Mode (PRIV State)

A work process has exhausted local user memory and switched to heap memory allocation, locking the work process specifically to a single user session.

Resolution

Monitor work processes in SM50 / SM66. Increase Extended Memory parameters (abap/heap_area_total) in RZ11 to prevent process lockups.

WORK PROCESS

CPIC-CALL_RECEIVE_ERROR

An active work process lost communication with an external system or gateway process during a CPIC/RFC transaction.

2. Enqueue Server & Lock Table Overflows

ENQUEUE

ENQUE_REQ_TOO_MANY_REQUESTS (Lock Table Full)

The Enqueue server lock table is completely filled up, preventing any new lock locks from being created by application processes.

Resolution

Inspect active lock entries in Transaction SM12. Increase profile parameter enque/table_size in RZ11 and restart the Enqueue Server.

ENQUEUE

SYSTEM_GNT_RELEASE_LOCK_FAILED

Occurs when a work process attempts to release a lock argument that was already deleted or not owned by the current transaction context.

3. SAP HANA Database & Memory Allocation Errors

HANA DB

HANA Out of Memory (OOM) / Allocation Failed

SAP HANA database engine ran out of physical or allocated memory (`global_allocation_limit`) while processing complex column-store queries or delta merges.

Resolution

Analyze memory allocation statements in HANA Studio / DBACockpit (ST04 / DB02). Cancel heavy unoptimized queries or increase global_allocation_limit in global.ini.

HANA DB

Column Store Delta Merge Failed

Automatic or forced Delta Merge operation failed due to insufficient memory space or concurrent database table locks.

Resolution

Check DB alerts in DBACockpit and manually trigger a forced delta merge via SQL: MERGE DELTA OF "TABLE_NAME".

HANA DB

SQL Error 129: Transaction Rollback (Deadlock Detected)

HANA Database engine automatically aborted a transaction because two or more threads were deadlocked waiting for database row locks.

4. System Log & Storage Space Faults

STORAGE

Tablespace Full (DB Error -1632 / ORA-01653)

Underlying relational database cannot allocate additional space for a table or index because the underlying tablespace volume is 100% full.

Resolution

Extend tablespace datafiles via DBACockpit / BRTOOLS or enable auto-extend mode on storage volumes.

BASIS

SAP Gateway Not Running (SAPGATEWAY_CANNOT_CONNECT)

Application server cannot establish communication with the SAP Gateway daemon process (`gwrd`).

Resolution

Verify gateway process status in SM51 / SMGW and verify TCP/IP port `33xx` connectivity.

BASIS

Update Task Stopped / Deactivated (SM13 Alerts)

SAP Update Service (UPD/UP2 work processes) has been automatically halted due to a database failure or critical error during asynchronous posting.
