  Cause:
  The error is usually caused by one of the following issues:
  
  
  Missing Configuration: The base heating value class has not been defined in the conversion group for the material or substance you are working with. This means that the system does not know how to convert the heating values for that specific material.
  
  
  Incorrect Material Master Data: The material master data may not be correctly set up, particularly in the area related to energy values or conversion factors.
  
  
  Conversion Group Issues: The conversion group itself may not be properly configured or may not include the necessary heating value classes.
  
  
  Solution:
  To resolve the O3311 error, you can follow these steps:
  
  
  Check Conversion Group Configuration:

  Review Material Master Data:
