• What is the cause and solution for SAP error message D4423 - SAP/OS400 active space roll management: User management - peak size ?

  The SAP error message D4423, which pertains to "SAP/OS400 active space roll management: User management - peak size," typically indicates that the peak size of the active space for a user has exceeded the defined limits. This can occur in environments where SAP is running on IBM i (formerly known as AS/400) systems.
  Cause:
  
  
  Exceeding Limits: The primary cause of this error is that the user has exceeded the maximum allowed size for the active space. This can happen due to:
  
  Large transactions or processes that require more memory than allocated.
  Inefficient coding or processing that leads to excessive memory usage.
  High concurrency or multiple users performing heavy operations simultaneously.
  
  
  
  Configuration Settings: The configuration settings for the active space may not be optimized for the workload, leading to frequent peak size issues.
  
  
  Solution:
  
  
  Increase Active Space Size:
  
  You can increase the maximum allowed size for the active space for the user. This can be done by adjusting the relevant parameters in the SAP system configuration.
  Use transaction code RZ10 to modify the profile parameters related to memory management, such as abap/heap_area_total or abap/heap_area_dia.
  
  
  
  Optimize Code and Processes:
  
  Review and optimize the ABAP code to ensure that it is efficient and does not consume excessive memory.
  Analyze the transactions that are causing the peak size to exceed limits and see if they can be optimized.
  
  
  
  Monitor and Analyze Usage:
  
  Use transaction SM50 or SM66 to monitor the active processes and their memory usage.
  Identify any long-running or resource-intensive processes that may be contributing to the issue.
  
  
  
  User Management:
  
  If the issue is specific to certain users, consider reviewing their roles and permissions to ensure they are not performing unnecessary heavy operations.
  
  
  
  Consult SAP Notes:
