Exchanges can be reversed from the History tab, and current loaned or borrowed items may be returned from the Current tab. Individual Loan & Borrow history entries cannot be reversed, but transactions within a date range can be removed using Delete Data.
From the Product menu, select Loan/Borrow & Exchanges.
Reverse an Exchange
Select the History tab, then right-click on the exchange and choose Reverse. Click Yes to accept and close the form.
Return a Current Loan or Borrow
From the Current tab, select the checkbox next to each returned item. From the toolbar, click 
Return. Click Yes to accept and close the form.
Additional Information:
From the History tab, individual transactions under the Loan & Borrow section cannot be reversed or returned. You can, however, remove transactions created between a specific date range using the Delete Data function found under the File menu. We recommend that you take a backup before doing so, as it is permanent.
