  The SAP error message ECH_PLA_CUSTOM004 with the description "Class &1 does not exist" typically indicates that the system is trying to reference a class (likely a classification class) that has not been defined or is not available in the system. This can occur in various contexts, such as when working with classification data, product master data, or during certain transactions that involve class assignments.
  Causes:
  
  Missing Class Definition: The class that is being referenced in the transaction or process does not exist in the system.
  Incorrect Class Name: There may be a typo or incorrect naming in the class reference.
  Authorization Issues: The user may not have the necessary authorizations to view or access the class.
  Transport Issues: If the class was recently transported from another system, it may not have been transported correctly or may not exist in the target system.

  Solutions:
  
  
  Check Class Existence:
