  Check Leading Parts: Go to the relevant transaction in SAP (such as MD61, MD02, or similar) to check the MRP settings for the specified set. Look for the leading parts defined for that MRP set.
  
  
  Remove Duplicate Leading Parts: If you find that there are multiple leading parts defined, you will need to remove or adjust the settings to ensure that only one leading part is designated. This may involve:
  
  Deleting the duplicate leading parts.
  Changing the configuration to assign a single leading part.
  
  
  
  Save Changes: After making the necessary adjustments, save your changes and re-run the MRP process to see if the error persists.
  
  
  Testing: It is advisable to test the MRP run after making changes to ensure that the issue is resolved and that the MRP calculations are functioning correctly.
