This typically occurs in scenarios where you are trying to use a custom class for data enrichment in MDG, but the class does not conform to the expected interface.
  Cause:
  
  Missing Interface Implementation: The specified class (denoted by &1 in the error message) does not implement the IF_USMD_ENRICHMENT_FEEDER interface. This interface is necessary for the class to be recognized as a valid feeder for data enrichment processes in MDG.
