  The SAP error message RSAR851 indicates that a Master Data InfoSource has been imported without a source system reference. This typically occurs in the context of SAP BW (Business Warehouse) when you are trying to load data from a source system, and the system cannot find the necessary reference to the source system for the InfoSource.
  Cause:
  
  Missing Source System Reference: The InfoSource was created or imported without a proper link to a source system. This can happen if the InfoSource was manually created or if there was an issue during the import process.
  Transport Issues: If the InfoSource was transported from another system, the transport might not have included the necessary source system references.
  Configuration Errors: There may be configuration errors in the source system or in the BW system that prevent the proper linking of the InfoSource to the source system.
  
  Solution:
  
  
  Check Source System Configuration:
