• What is the cause and solution for SAP error message /STTPEC/MSG895 - MEMSTAT: &1 byte used in session ?

  The SAP error message /STTPEC/MSG895 MEMSTAT: &1 byte used in session indicates that a specific session in the SAP system is consuming a significant amount of memory. This can lead to performance issues or even session termination if the memory usage exceeds certain thresholds.
  Cause:
  
  
  High Memory Consumption: The session is using a large amount of memory, which could be due to:
  
  Large data processing tasks.
  Inefficient coding or logic in ABAP programs.
  Memory leaks in custom programs or transactions.
  Large internal tables or data structures being processed.
  
  
  
  Configuration Issues: The system may not be optimally configured for memory usage, leading to excessive memory consumption in certain sessions.
  
  
  Concurrent Sessions: Multiple sessions running simultaneously may lead to overall high memory usage, affecting individual sessions.
  
  
  Solution:
  
  
  Analyze Memory Usage:
  
  Use transaction ST02 (Tune Summary) to check for memory bottlenecks and analyze memory usage.
  Use transaction SM50 to monitor active processes and their memory consumption.
  
  
  
  Optimize ABAP Code:
  
  Review and optimize any custom ABAP programs that are running in the session. Look for:
  
  Unnecessary large internal tables.
  Inefficient loops or data processing logic.
  Use of SELECT * instead of selecting only required fields.
  
  
  
  
  
  Adjust System Parameters:
  
  Review and adjust memory-related parameters in the SAP profile (e.g., abap/heap_area_total, abap/heap_area_dia, etc.) to ensure they are set appropriately for your workload.
  
  
  
  Session Management:
  
  Limit the number of concurrent sessions for users if possible.
  Encourage users to log off sessions that are no longer needed.
  
  
  
  Monitor and Tune:
  
  Regularly monitor memory usage and performance metrics to identify trends and potential issues before they become critical.
  
  
  
  Consult SAP Notes:
  
  Check for any relevant SAP Notes that may address known issues or provide additional guidance on memory management.
  
  
  
  Related Information:
  
  
  Transaction Codes:
  
  ST02: Tune Summary for memory analysis.
  SM50: Monitor active processes.
  SM66: Global overview of processes across instances.
  
  
  
  SAP Documentation: Refer to SAP Help Portal for documentation on memory management and performance tuning.
  
  
  Performance Tuning: Consider engaging with SAP Basis or performance tuning experts if the issue persists or if you are unable to identify the root cause.
  
  
  By following these steps, you should be able to address the memory consumption issue indicated by the error message and improve the performance of the affected session.
