Is it possible to create negative arrears without JDE paying the employee?

Hi there,

We have retirees who pay 50% of their benefits.  Our JDE (9.1) is set up to arrear the employee portion and when a cheque (or check )  the Payroll Coordinator draws down the arrears. 

We're running into the issue that the arrears may not yet be equal to or greater than the cheque.  That creates a negative arrears situation and JDE attempts to pay the employee the amount of the negative arrears.  This causes major inefficiencies as now staff have to defer the entry and monitor the arrears until there is enough to cover the cheque.  Is there any way to suppress the payment of negative arrears to employees?  And if not, is there any way to suppress any net pay to an employee as these retirees will never receive net pay.  Only non-cash
