• What is the cause and solution for SAP error message /SAPAPO/CDPSOPT777 - Available memory on optimization server is low (available: &1%) ?

  The SAP error message /SAPAPO/CDPSOPT777 Available memory on optimization server is low (available: &1%) indicates that the optimization server in SAP Advanced Planning and Optimization (APO) is running low on available memory. This can lead to performance issues or even failures in executing optimization tasks.
  Causes:
  
  High Load: The optimization server may be handling too many requests or large datasets, consuming more memory than available.
  Configuration Issues: The server may not be configured with sufficient memory resources to handle the current workload.
  Memory Leaks: There could be memory leaks in the optimization processes or in the underlying system.
  Insufficient Hardware Resources: The physical or virtual server may not have enough RAM allocated to meet the demands of the APO processes.
  Long-running Processes: Long-running optimization jobs may hold onto memory longer than necessary.
  
  Solutions:
  
  
  Increase Memory Allocation:
  
  Review and increase the memory allocation for the optimization server in the SAP system settings. This can be done in the SAP GUI under the transaction RZ10 or RZ11 for profile parameters.
  Consider increasing the physical memory of the server if it is a hardware limitation.
  
  
  
  Optimize Data and Processes:
  
  Review the data being processed and consider optimizing it. This may involve reducing the size of datasets or breaking down large optimization tasks into smaller ones.
  Schedule optimization jobs during off-peak hours to reduce the load on the server.
  
  
  
  Monitor and Tune Performance:
  
  Use transaction ST02 (Tune Summary) to monitor memory usage and identify any bottlenecks.
  Use transaction SM37 to check for long-running jobs and analyze their memory consumption.
  
  
  
  Check for Memory Leaks:
  
  Investigate if there are any known issues or patches related to memory leaks in the version of SAP APO you are using. Apply any relevant support packages or notes from SAP.
  
  
  
  Review System Logs:
  
  Check system logs for any additional error messages or warnings that may provide more context about the memory issue.
  
  
  
  Consult SAP Notes:
  
  Search for relevant SAP Notes in the SAP Support Portal that may address this specific error or provide guidance on memory management in APO.
  
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for APO and optimization server configuration for best practices.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have implemented.
  Performance Monitoring Tools: Consider using SAP Solution Manager or other performance monitoring tools to keep track of system performance and resource utilization.
  
  By addressing the memory issue proactively, you can help ensure that the optimization server runs efficiently and effectively, minimizing disruptions to your planning processes.
