• What is the cause and solution for SAP error message /SCWM/WAVE095 - Parallel processing is not possible because of system load ?

  The SAP error message /SCWM/WAVE095 Parallel processing is not possible because of system load typically occurs in the context of SAP Extended Warehouse Management (EWM) when the system is unable to execute parallel processing for wave management due to high system load. This can happen for various reasons, including resource constraints, high transaction volume, or system configuration issues.
  Causes:
  
  High System Load: The system may be experiencing high CPU or memory usage, which prevents it from processing multiple tasks in parallel.
  Configuration Settings: The settings for parallel processing in the EWM system may not be optimized or may be set too low.
  Database Performance: Slow database performance can lead to delays in processing, causing the system to restrict parallel processing.
  Lock Contention: If multiple processes are trying to access the same resources, it can lead to contention and slow down processing.
  Background Jobs: Other background jobs running in the system may be consuming resources, leading to a bottleneck.
  
  Solutions:
  
  Monitor System Performance: Use transaction codes like ST03N, ST06, or SM66 to monitor system performance and identify any bottlenecks.
  Adjust Parallel Processing Settings: Review and adjust the settings for parallel processing in the EWM configuration. This may involve increasing the number of parallel processes allowed.
  Optimize Database Performance: Ensure that the database is optimized for performance. This may include indexing, updating statistics, or checking for long-running queries.
  Schedule Background Jobs: If there are background jobs that are consuming significant resources, consider rescheduling them to off-peak hours.
  Increase System Resources: If the system is consistently under heavy load, consider upgrading hardware resources (CPU, memory) or optimizing the existing infrastructure.
  Check for Locks: Use transaction SM12 to check for locks that may be causing contention and resolve any issues found.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide guidance on performance tuning for EWM.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have found.
  Performance Tuning Guides: Refer to SAP's performance tuning guides for EWM and the underlying database to ensure best practices are being followed.
  
  By addressing the underlying causes and implementing the suggested solutions, you should be able to resolve the error and improve the performance of parallel processing in your SAP EWM system.
