• What is the cause and solution for SAP error message CNV20551817 - System Memory Low. Please increase limit for system memory parameters. ?

  The SAP error message CNV20551817: System Memory Low. Please increase limit for system memory parameters typically indicates that the SAP system is running low on memory resources, which can affect performance and lead to failures in processing tasks. This error is often encountered during data migration or conversion processes, particularly when using tools like SAP S/4HANA Migration Cockpit or SAP Data Services.
  Causes:
  
  Insufficient Memory Allocation: The SAP system may not have enough memory allocated to handle the current workload, especially during data-intensive operations.
  High Workload: The system may be experiencing a high volume of concurrent processes or transactions that consume significant memory.
  Configuration Issues: The memory parameters in the SAP system profile may not be optimally configured for the current workload.
  Memory Leaks: There could be memory leaks in the application or custom code that are consuming memory over time.
  
  Solutions:
  
  
  Increase Memory Parameters:
  
  You can increase the memory limits in the SAP profile parameters. The key parameters to consider are:
  
  abap/heap_area_dia: This parameter controls the memory for dialog work processes.
  abap/heap_area_nondia: This parameter controls the memory for non-dialog work processes.
  abap/heap_area_total: This parameter sets the total heap area for the ABAP runtime environment.
  
  
  To change these parameters, you can use transaction RZ10 to edit the instance profile and then restart the SAP system for the changes to take effect.
  
  
  
  Monitor and Optimize Workload:
  
  Use transaction ST03N to analyze the workload and identify any long-running or resource-intensive processes that can be optimized or scheduled during off-peak hours.
  
  
  
  Check for Memory Leaks:
  
  Use transaction ST22 to check for dumps that may indicate memory leaks or issues in custom code. Review and optimize any problematic code.
  
  
  
  Increase Hardware Resources:
  
  If the system consistently runs low on memory, consider upgrading the hardware resources (RAM) of the server hosting the SAP system.
  
  
  
  Review Background Jobs:
  
  Check for any background jobs that may be consuming excessive memory and adjust their scheduling or resource allocation.
  
  
  
  Related Information:
  
  SAP Notes: Check for relevant SAP Notes that may provide additional guidance or patches related to memory management.
  SAP Community: Engage with the SAP Community forums for insights from other users who may have encountered similar issues.
  System Monitoring Tools: Utilize tools like SAP Solution Manager or third-party monitoring solutions to keep track of system performance and memory usage.
  
  Conclusion:
  Addressing the CNV20551817 error involves a combination of increasing memory parameters, optimizing workloads, and ensuring that the system is adequately resourced. Regular monitoring and maintenance can help prevent this issue from recurring.
