Per your info I am assuming the original check posted as the Employees earnings and appeared on the W2 for 2014 year. And since the original check was not voided, and the employee got another check (reissue as you state) I am assuming as a payroll check, I am thinking the 2nd check updated the employees ytd earnings and will show on a W2 in 2014 as well. You could set up a new field as a deduction called Advance, give it a GL account, and post the Net check of the reissued check as a negative value in the Advance field on their next paycheck.
