• What is the cause and solution for SAP error message /SAPAPO/SNPOPT287 - Fixed partial problem cannot be solved ?

  The SAP error message /SAPAPO/SNPOPT287 Fixed partial problem cannot be solved typically occurs in the context of SAP Advanced Planning and Optimization (APO), particularly when dealing with optimization problems in Supply Network Planning (SNP) or Production Planning and Detailed Scheduling (PP/DS). This error indicates that the optimization problem cannot be solved due to certain constraints or settings in the planning run.
  Causes:
  
  
  Infeasible Constraints: The optimization problem may have constraints that cannot be satisfied simultaneously. This could be due to:
  
  Capacity constraints that are too tight.
  Demand that exceeds supply capabilities.
  Conflicting constraints that prevent a feasible solution.
  
  
  
  Data Issues: Incorrect or incomplete master data, such as:
  
  Missing or incorrect resource capacities.
  Incorrectly defined product master data.
  Issues with transportation lanes or lead times.
  
  
  
  Configuration Issues: The configuration settings in the SNP or PP/DS may not be set up correctly, leading to an inability to find a feasible solution.
  
  
  Fixed Orders: If there are fixed orders or fixed production quantities that are too high or conflicting with other orders, it can lead to infeasibility.
  
  
  Solutions:
  
  
  Review Constraints: Check the constraints defined in the planning run. Ensure that they are realistic and can be satisfied given the available resources and demand.
  
  
  Check Master Data: Verify that all relevant master data is complete and accurate. This includes:
  
  Resource capacities.
  Product master data.
  Transportation lanes and lead times.
  
  
  
  Adjust Planning Parameters: Modify the planning parameters or settings to allow for more flexibility in the optimization process. This may include:
  
  Relaxing certain constraints.
  Adjusting fixed order quantities.
  
  
  
  Analyze the Planning Run: Use the planning analysis tools available in SAP APO to identify where the infeasibility is occurring. This can help pinpoint specific issues that need to be addressed.
  
  
  Run a Simplified Model: If the problem persists, try running a simplified version of the planning model to isolate the issue. Gradually reintroduce complexity to identify the specific cause of the error.
  
  
  Consult SAP Notes: Check for any relevant SAP Notes or updates that may address known issues related to this error message.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as /SAPAPO/SNP1 for SNP planning and /SAPAPO/DP for demand planning.
  SAP Help Documentation: Refer to the official SAP documentation for detailed guidance on configuration and troubleshooting in APO.
  Community Forums: Engage with SAP community forums or support channels for additional insights and shared experiences from other users facing similar issues.
  
  By systematically addressing the potential causes and applying the suggested solutions, you should be able to resolve the error message and successfully complete your planning run in SAP APO.
