If OLR powers your company website you may have the option to show recent transactions on your web site agent page.
To manually add a recent transaction go to My Listings > Manage Listings and add the listing as Internal (for rentals) or Buyer's Broker (for sales).
Enter only the required information (the amount of information that appears under the Recent Transactions section is limited to a few fields). Enter the listing status as Active, submit the listing and then set the status to either Sold or Rented. The listing will shortly appear as a Recent Transaction on your agent page.
