  The SAP error message RSB4HANA173 indicates that the system is unable to determine the name of a class method, which typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when dealing with ABAP code or data extraction processes.
  Cause:
  
  Missing or Incorrect Class Definition: The class or method that is being referenced may not be defined correctly in the ABAP code. This could be due to a typo, a missing class, or an incorrect method name.
  Transport Issues: If the code was recently transported from one system to another (e.g., from development to production), there may be inconsistencies or missing objects in the target system.
  Authorization Issues: The user executing the code may not have the necessary authorizations to access the class or method.
