Manage, Items Field Descriptions

Field Description
Remove bids... Removes the bid submitted for the auction item(s).
Fill By Rules When selected Fill By Rules is used in the Bid Management pane to test the win order of a Preference auction. This is optional, since the Auction will automatically evaluate each bidder’s preferences and assigns the winning items starting from the most desired and available auction item.
  For example, suppose that you want to determine who will win 4th of July in a time-off Preference Auction before the Auction is resolved. Since the process of evaluating each bidder’s choices can quickly become overwhelming, the auction’s Fill by rules... function helps troubleshoot the win order aspect by displaying the bidders who have bid along with their bid values (1) 1st Choice, (2) 2nd Choice...
Fill By Person When selected Fill By Person is used in the Bid Management pane. Rare usage. For example, the Fill by person... function can be used to select multiple bidders and test who will win the auction item.
