• What is the cause and solution for SAP error message SEPMH_DG023 - Lambda value for Poisson distribution has not yet been specified ?

  The SAP error message SEPMH_DG023 indicates that a lambda value for the Poisson distribution has not been specified in the context of a statistical analysis or calculation that requires it. The Poisson distribution is commonly used in scenarios where you are modeling the number of events occurring within a fixed interval of time or space, and the lambda (?) parameter represents the average rate of occurrence of these events.
  Cause:
  The error typically arises when:
  
  A statistical function or report that requires a Poisson distribution is being executed without a defined lambda value.
  The configuration or input data for the statistical analysis is incomplete or incorrect.
  There may be a missing or misconfigured parameter in the relevant transaction or program.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Specify the Lambda Value:
  
  Ensure that the lambda value is defined in the relevant configuration or input fields. This may involve checking the parameters in the transaction or report you are running.
  
  
  
  Check Configuration:
  
  Review the configuration settings for the statistical analysis or report. Make sure that all required parameters, including the lambda value, are correctly set.
  
  
  
  Review Input Data:
  
  If the lambda value is supposed to be derived from input data, ensure that the data is complete and correctly formatted. Check for any missing values or inconsistencies.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation or help resources related to the specific transaction or report you are using. This may provide insights into how to correctly specify the lambda value.
  
  
  
  Contact Support:
  
  If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting with an SAP expert who can provide assistance based on your specific system configuration and requirements.
  
  
  
  Related Information:
  
  Poisson Distribution: Understand the basics of the Poisson distribution, including its applications and how the lambda parameter is used to model event occurrences.
  SAP Documentation: Look for SAP notes or documentation related to the specific module or function you are using, as they may contain additional troubleshooting steps or updates.
  Statistical Analysis in SAP: Familiarize yourself with how SAP handles statistical functions and the requirements for running analyses that involve distributions.
  
  By following these steps, you should be able to address the SEPMH_DG023 error and successfully execute your statistical analysis.
