• What is the cause and solution for SAP error message /SAPAPO/PINV115 - Calc. &1, &2(VCL) with const. Poisson distribution with price scaling ?

  The SAP error message /SAPAPO/PINV115 Calc. &1, &2(VCL) with const. Poisson distribution with price scaling 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 Poisson distribution model, particularly when price scaling is involved.
  Cause:
  
  Data Issues: The error may arise due to missing or incorrect data in the planning book or master data. This could include issues with historical data, such as insufficient data points for the Poisson distribution to be calculated accurately.
  Configuration Issues: The configuration settings for the demand planning or the specific planning book may not be set up correctly to handle the Poisson distribution with price scaling.
  Modeling Issues: If the model being used for forecasting is not appropriate for the data or if the parameters for the Poisson distribution are not correctly defined, this can lead to calculation errors.
  Price Scaling Problems: If the price scaling factor is not defined or is set to an inappropriate value, it can cause issues in the calculation process.
  
  Solution:
  
  Check Data: Review the historical data used for the calculation. Ensure that there is sufficient data for the Poisson distribution to be calculated. Look for any missing values or anomalies in the data.
  Review Configuration: Check the configuration settings in the planning book and ensure that the settings for the Poisson distribution and price scaling are correctly defined.
  Adjust Parameters: If you are using a custom model, review the parameters for the Poisson distribution and ensure they are set correctly. You may need to adjust the parameters based on the characteristics of your data.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on configuring the Poisson distribution and price scaling in your version of SAP APO.
  Testing: After making adjustments, run a test calculation to see if the error persists. If it does, further investigation may be needed into the specific data or configuration settings.
