• What is the cause and solution for SAP error message /SCMTMS/PLN_OPT_APP777 - Available memory on optimization server is low (available: &1%) ?

  The SAP error message /SCMTMS/PLN_OPT_APP777 indicates that the available memory on the optimization server is low, which can affect the performance of the Transportation Management System (TMS) optimization processes. 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 or the size of the data being processed.
  High Workload: A large number of optimization requests or complex optimization scenarios can consume significant memory resources.
  Memory Leaks: There may be memory leaks in the optimization application or related processes that are causing memory to be consumed without being released.
  Configuration Issues: The server may not be configured optimally for the workload it is handling.
  
  Solutions:
  
  
  Increase Memory Allocation:
  
  Review the memory settings for the optimization server and increase the allocated memory if possible. This can often be done in the server configuration settings.
  
  
  
  Optimize Data Processing:
  
  Reduce the size of the data being processed in a single optimization run. This can be done by breaking down large optimization requests into smaller, more manageable ones.
  Review the optimization parameters and settings to ensure they are not overly complex for the current server capacity.
  
  
  
  Monitor and Manage Workload:
  
  Monitor the workload on the optimization server to identify peak times and adjust scheduling of optimization tasks accordingly.
  Implement load balancing if multiple optimization servers are available.
  
  
  
  Check for Memory Leaks:
  
  Investigate the application for potential memory leaks. This may require debugging or profiling the application to identify areas where memory is not being released properly.
  
  
  
  Server Upgrade:
  
  If the current server hardware is consistently running low on memory, consider upgrading the server hardware to provide more resources.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes or patches that may address known issues related to memory management in the optimization server.
  
  
  
  Related Information:
  
  SAP Documentation: Review the official SAP documentation for TMS and optimization server configuration for best practices and guidelines.
  System Monitoring Tools: Utilize SAP monitoring tools (like SAP Solution Manager) to keep track of system performance and memory usage.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have implemented.
  
  By addressing the memory issue proactively, you can help ensure that the optimization processes in SAP TMS run smoothly and efficiently.
