  Different planning versions or scenarios have conflicting efficiency values.
  There are overlapping or duplicate entries in the master data for the resource.
  
  
  
  Incorrect Configuration: The configuration of the resource or production process may not be set up correctly, leading to multiple efficiencies being assigned.

  Remove Duplicates:
  
  If you find multiple efficiency records, determine which one is correct and remove or deactivate the duplicates.
  
  
  
  Review Master Data:
  
  Check the master data for the resource and ensure that it is correctly configured. Look for any inconsistencies or errors in the data.
  
  
  
  Check Planning Versions:
  
  If you are using multiple planning versions, ensure that the efficiency values are consistent across these versions.
