• What is the cause and solution for SAP error message /SAPAPO/SNPOPT808 - Starting primal simplex algorithm ?

  The SAP error message /SAPAPO/SNPOPT808 Starting primal simplex algorithm typically occurs in the context of SAP Advanced Planning and Optimization (APO) when the system is attempting to solve an optimization problem using the primal simplex algorithm. This message is not necessarily an error but rather an informational message indicating that the algorithm is being initiated.
  Possible Causes:
  
  Large Problem Size: The optimization problem being solved may be large or complex, which can lead to longer processing times.
  Data Issues: There may be issues with the input data, such as missing values, incorrect configurations, or inconsistencies in the planning data.
  Resource Constraints: The system may be experiencing resource constraints (CPU, memory) that could affect the performance of the optimization process.
  Configuration Settings: The settings for the optimization algorithm may not be optimal for the specific problem being solved.
  
  Solutions:
  
  Monitor Performance: If the message appears frequently, monitor the performance of the optimization process. Check if it is taking an unusually long time to complete.
  Check Input Data: Review the input data for completeness and correctness. Ensure that all necessary data is available and properly configured.
  Optimize Configuration: Review the configuration settings for the optimization algorithm. Adjust parameters if necessary to improve performance.
  Increase System Resources: If resource constraints are suspected, consider increasing the system's CPU or memory allocation.
  Run in Background: If the optimization process is taking too long, consider running it in the background to avoid blocking other processes.
  Consult Documentation: Refer to SAP documentation or notes related to the specific version of APO you are using for any known issues or recommendations.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any specific issues related to the primal simplex algorithm or optimization in APO.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as /SAPAPO/OPTIMIZE for running optimization jobs.
  Performance Tuning: Look into performance tuning guides for SAP APO to enhance the efficiency of optimization processes.
  SAP Community: Engage with the SAP Community for insights and experiences from other users who may have encountered similar messages.
  
  If the message persists or leads to actual errors in the optimization process, it may be beneficial to contact SAP support for further assistance.
