  Cause:
  
  
  Missing Table: The error suggests that the system is trying to access a table named WBRFN, which does not exist in the database. This could be due to:
  
  The table not being created or activated in the system.
  A misconfiguration in the data migration setup.
  An issue with the data model or mapping configuration.
