  SAP Error Message:
  WZRE_PRX001: Mapping inbound class &1 for use case type &2 is not existing
  
  
  Cause:
  This error occurs when the system tries to process an inbound message or data using a specific inbound class (handler class) for a given use case type, but the mapping for this inbound class does not exist or is not maintained in the system.
  In SAP PI/PO or SAP Cloud Integration scenarios, inbound processing classes are used to handle incoming messages based on the use case type. If the system cannot find the appropriate inbound class mapping for the specified use case type, it throws this error.
  Typical reasons:
  
  The inbound class has not been configured or assigned for the use case type.
  The configuration was deleted or not transported properly.
  Custom inbound class was created but not registered in the system.
  Incorrect use case type or inbound class name in the configuration.
