  The SAP error message R3063, which states "Hierarchy class & not defined in the source system," typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when there is an issue with the hierarchy definition in the source system. This error indicates that the system is unable to find a specific hierarchy class that is expected to be defined in the source system.
  Cause:
  
  Missing Hierarchy Definition: The hierarchy class that is referenced in the data extraction or reporting process is not defined in the source system.
