• What is the cause and solution for SAP error message /SAPAPO/SNPOPT172 - Production process model/PDS &1 at loc. &2: Larger no. lots costs less ?

  The SAP error message /SAPAPO/SNPOPT172 typically occurs in the context of Advanced Planning and Optimization (APO) when dealing with production process models (PDS) in SAP. This error indicates that the system has detected a situation where the cost of producing a larger number of lots is less than the cost of producing a smaller number of lots. This can happen due to various reasons related to the configuration of the production process, cost settings, or the way the production process is modeled.
  Cause:
  
  
  Cost Configuration: The cost structure for the production process may be set up in such a way that economies of scale are not properly reflected. For example, fixed costs may be too high for smaller lot sizes, making larger lot sizes more cost-effective.
  
  
  Production Process Model (PDS) Settings: The settings in the PDS may not align with the expected cost behavior. This could include incorrect lot size settings, cost parameters, or other relevant configurations.
  
  
  Lot Size Calculation: The system may be calculating the lot sizes based on certain parameters that lead to this discrepancy in costs.
  
  
  Master Data Issues: There may be issues with the master data related to the materials, resources, or production processes that affect cost calculations.
  
  
  Solution:
  
  
  Review Cost Settings: Check the cost settings in the production process model. Ensure that the fixed and variable costs are set correctly to reflect the actual cost behavior of production.
  
  
  Adjust Lot Size Parameters: Review and adjust the lot size parameters in the PDS. Ensure that the lot size calculations are aligned with the expected production costs.
  
  
  Analyze PDS Configuration: Look into the PDS configuration to ensure that it accurately reflects the production process. This includes checking the routing, work centers, and any other relevant settings.
  
  
  Check Master Data: Verify the master data for the materials and resources involved in the production process. Ensure that all relevant data is accurate and up-to-date.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on configuring production process models and cost settings.
  
  
  Engage with SAP Support: If the issue persists, consider reaching out to SAP support for assistance. They can provide insights based on the specific configuration and version of your SAP system.
  
  
  Related Information:
  
  SAP APO Documentation: Review the official SAP documentation for APO, particularly sections related to production planning and process modeling.
  Costing in SAP: Familiarize yourself with how costing works in SAP, including fixed and variable costs, and how they impact production planning.
  Training and Resources: Consider training sessions or resources on SAP APO to better understand the intricacies of production planning and optimization.
  
  By addressing the underlying causes and following the suggested solutions, you should be able to resolve the error message and ensure that your production planning processes are functioning correctly.
