• What is the cause and solution for SAP error message /SAPAPO/PINV116 - Calculate &1, &2 (VCL) with non-constant Poisson distr. w/o price scales ?

  The SAP error message /SAPAPO/PINV116 Calculate &1, &2 (VCL) with non-constant Poisson distr. w/o price scales typically occurs in the context of SAP Advanced Planning and Optimization (APO) when there is an issue with the calculation of demand or supply using a non-constant Poisson distribution without price scales. This error can arise during the planning process, particularly in demand planning or inventory management scenarios.
  Cause:
  
  Non-constant Poisson Distribution: The error indicates that the system is trying to calculate a forecast or planning scenario using a non-constant Poisson distribution, which is not properly configured or supported in the current context.
  Missing Price Scales: The error also suggests that the calculation is being attempted without the necessary price scales, which are often required for certain types of demand forecasting or planning calculations.
  Configuration Issues: There may be issues with the configuration of the planning book, data settings, or the characteristics of the product being analyzed.
  Data Integrity: There could be missing or incorrect data in the master data or transaction data that is required for the calculation.
  
  Solution:
  
  Check Configuration: Review the configuration settings for the planning book and the characteristics of the product. Ensure that the Poisson distribution settings are correctly defined.
  Define Price Scales: If the calculation requires price scales, ensure that they are defined and correctly assigned to the relevant products or planning scenarios.
  Review Master Data: Check the master data for the product in question. Ensure that all necessary data is complete and accurate, including historical sales data, which is often used for forecasting.
  Use Constant Poisson Distribution: If applicable, consider switching to a constant Poisson distribution if the non-constant version is not necessary for your planning scenario.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on configuring Poisson distributions and price scales in your version of SAP APO.
  SAP Notes and Support: Check for any relevant SAP Notes that may address this specific error or provide patches or updates that could resolve the issue.
  
  Related Information:
  
  SAP APO Documentation: Review the official SAP documentation for APO, particularly sections related to demand planning and statistical forecasting.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have found.
  Training and Resources: Consider additional training or resources on SAP APO to better understand the statistical forecasting methods and their configurations.
  
  If the issue persists after trying the above solutions, it may be beneficial to involve your SAP support team or a consultant with expertise in SAP APO for further assistance.
