  The SAP error message MDG_BS_BP020 with the description "Class &1 does not exist" typically occurs in the context of Master Data Governance (MDG) for Business Partners (BP). This error indicates that the system is trying to reference a class (usually a classification or a business partner category) that has not been defined or does not exist in the system.
  Cause:
  
  Missing Class Definition: The class that is being referenced in the process does not exist in the system. This could be due to a configuration issue or an oversight during the setup of business partner data.
  Incorrect Configuration: The configuration settings for business partner classes may not have been properly set up, leading to the system not being able to find the specified class.
  Data Migration Issues: If data was migrated from another system, there may have been issues during the migration process that resulted in missing classes.

  Solution:
  
  
  Check Class Definition:

  Data Consistency Check:
