Just a note for those who are in a province where vacation pay is accrued on vacation pay paid out (as is the case in Saskatchewan where I work) - the item you create cannot be deduction item but rather should be an addition item (where you will manually enter a negative number).  Reason being is that Deduction items are not in the list of items upon which you can check to accrue vacation pay.  So the procedure described above, will create another Vacation accrual, but only on the VacPay - Accrual Paid out item.  Since you want the entire transaction to be 0.00, the only way to get an offsetting vacation accrual amount for the adjustment, is to enter the adjustment payroll item as an Addition.
