If Parts Library Updates > Notify on each duplicate part number is selected in the Options window, the Duplicate Part window opens when a duplicate part is encountered during the updating of part data in either a Prediction Parts Library file or System file. You click Update to update the part data or Ignore to continue without making a change to the part data. If you select Apply to all prior to clicking Update or Ignore, the action that you choose is applied to each duplicate part encountered during this update.
