Expense Payment Cancellation question

Hi All,

I hvae a question regarding the Expense Payment cancellation accounting entries. We issued a Check to an employee and he never received it (created a new exp report and paid with ACH). We decided to Void and Do Not Reissue/Close Liability. When we do this, getting beloow message " Warning -- Treasure or Expense transaction payment is being processed (7015,406). This is a Treasure or Expense transaction payment, you will need to go back to Treasure or Expense to manually reverse any accounting entries affected by this process.  Proceed?" We clicked OK and proceeded. Posted the Cancel payment in EX. How do we manually reverse the accounting entries?
