• What is the cause and solution for SAP error message /SAPAPO/PINV113 - Calc. &1, &2(VCL) with not-const. normal distribution with price scaling ?

  The SAP error message /SAPAPO/PINV113 Calc. &1, &2(VCL) with not-const. normal 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 a forecast or planning scenario that involves a non-constant normal distribution and price scaling.
  Cause:
  
  
  Non-Constant Normal Distribution: This error indicates that the system is trying to calculate a forecast using a normal distribution that is not constant. In other words, the parameters of the normal distribution (mean and standard deviation) may not be stable or consistent over the periods being analyzed.
  
  
  Price Scaling Issues: The error may also arise if there are issues with how prices are being scaled in the forecast model. If the price data is inconsistent or not properly configured, it can lead to calculation errors.
  
  
  Data Quality: Poor data quality, such as missing values, outliers, or incorrect historical data, can also trigger this error.
  
  
  Configuration Issues: There may be configuration issues in the forecasting model or settings that are not compatible with the data being processed.
  
  
  Solution:
  
  
  Review Data: Check the historical data for the product or planning object in question. Ensure that there are no missing values, outliers, or inconsistencies that could affect the normal distribution calculations.
  
  
  Adjust Forecast Model: If you are using a specific forecasting model that requires a constant normal distribution, consider switching to a different model that can handle non-constant distributions or adjust the parameters of the current model.
  
  
  Check Price Scaling Configuration: Review the configuration settings related to price scaling in your forecasting model. Ensure that the price data is correctly set up and that the scaling factors are appropriate.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling normal distribution calculations and price scaling in your version of SAP APO.
  
  
  Test with Simplified Data: If possible, test the forecasting model with a simplified dataset to isolate the issue. This can help determine if the problem is with the data or the model configuration.
  
  
  Seek Expert Help: If the issue persists, consider reaching out to SAP support or consulting with an SAP APO expert who can provide more tailored assistance based on your specific configuration and data.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide patches and updates.
  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 Documentation: Ensure that users involved in forecasting and planning are adequately trained on the tools and methodologies used in SAP APO to minimize errors related to data handling and model configuration.
  
  By following these steps, you should be able to identify the root cause of the error and implement a solution to resolve it.
