• What is the cause and solution for SAP error message /SAPAPO/CDPSOPT100 - Not enough memory ?

  The SAP error message /SAPAPO/CDPSOPT100 Not enough memory typically occurs in the context of SAP Advanced Planning and Optimization (APO) when the system runs out of memory while trying to execute a planning run or optimization task. This can happen due to various reasons, including large data volumes, inefficient memory allocation, or system configuration issues.
  Causes:
  
  Large Data Volume: The planning run may involve a large amount of data that exceeds the available memory.
  Insufficient Memory Allocation: The SAP system may not have enough memory allocated to handle the optimization task.
  Inefficient Queries: Poorly designed queries or planning models that require excessive memory.
  System Configuration: The SAP system may not be optimally configured for the workload it is handling.
  Background Jobs: Other background jobs running simultaneously may consume memory resources.
  
  Solutions:
  
  
  Increase Memory Allocation:
  
  Adjust the memory settings in the SAP profile parameters. You can increase the abap/heap_area_total and abap/heap_area_dia parameters to allocate more memory for ABAP programs.
  Consider increasing the rdisp/PG_MAXFS parameter to allow for larger memory allocation for the dispatcher.
  
  
  
  Optimize Data Volume:
  
  Reduce the amount of data being processed in a single planning run. This can be done by filtering data or breaking down the planning run into smaller segments.
  Archive old or unnecessary data to free up memory.
  
  
  
  Review and Optimize Queries:
  
  Analyze and optimize the queries used in the planning run to ensure they are efficient and do not consume excessive memory.
  
  
  
  Check System Configuration:
  
  Review the overall system configuration and ensure that it is optimized for the workload. This may involve consulting with your SAP Basis team.
  
  
  
  Monitor Background Jobs:
  
  Check for other background jobs that may be consuming memory and consider scheduling them at different times to reduce memory contention.
  
  
  
  Use SAP Notes:
  
  Check for any relevant SAP Notes that may address this specific error or provide patches that improve memory management in APO.
  
  
  
  Upgrade Hardware:
  
  If the issue persists and is due to hardware limitations, consider upgrading the server's RAM or moving to a more powerful server.
  
  
  
  Related Information:
