• What is the cause and solution for SAP error message /SAPAPO/OPT_VSR_MSG777 - Available memory on optimization server is low (available: &1%) ?

  The SAP error message /SAPAPO/OPT_VSR_MSG777 indicates that the available memory on the optimization server is low, which can affect the performance of optimization tasks in SAP Advanced Planning and Optimization (APO). Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Insufficient Memory Allocation: The optimization server may not have enough memory allocated to handle the current workload.
  High Workload: A large number of optimization tasks or complex optimization problems can consume significant memory resources.
  Memory Leaks: There may be memory leaks in the optimization processes or other related applications that are consuming memory over time.
  Configuration Issues: The server may not be configured optimally for the workload it is handling.
  
  Solutions:
  
  
  Increase Memory Allocation:
  
  Review and increase the memory settings for the optimization server. This can typically be done in the SAP system configuration settings.
  Check the parameters related to memory allocation in the SAP system (e.g., rdisp/PG_MAXFS, rdisp/PG_MAXFS, etc.) and adjust them as necessary.
  
  
  
  Optimize the Optimization Tasks:
  
  Review the optimization tasks being executed. If possible, break down large tasks into smaller ones to reduce memory consumption.
  Analyze the data being processed to ensure that only necessary data is included in the optimization tasks.
  
  
  
  Monitor and Manage Workload:
  
  Use transaction codes like SM37 to monitor background jobs and identify any long-running or resource-intensive jobs that may be consuming memory.
  Schedule optimization tasks during off-peak hours to reduce the load on the server.
  
  
  
  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 patches or updates.
  
  
  
  Server Upgrade:
  
  If the current hardware is consistently running low on memory, consider upgrading the server hardware to provide more memory resources.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide guidance on memory management in APO.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like RSCUSTV10 for customizing settings and RSPFPAR for profile parameters.
  SAP Basis Team: Collaborate with your SAP Basis team to ensure that the server is configured correctly and to assist with any necessary changes to memory settings.
  Performance Monitoring Tools: Utilize SAP performance monitoring tools to analyze memory usage and identify bottlenecks in the system.
  
  By addressing the memory allocation and workload management, you can mitigate the occurrence of this error and improve the performance of your optimization tasks in SAP APO.
