Zero dollar paycheck

Summary:

We have had a few cases in the past where an employee elects additional tax withholding but did not earn enough pay to cover the additional taxes. The system will take out every earned dollar and put it to the taxes which leaves them with a $0 check. When we run costing on it we get an error as it tries to cost the full amount of the additional withholding, it does not cost the actual tax that was withheld.

Currently we are now looking through every check to make sure that an employee has some net pay if they worked hours and if not we contact the employee to update their withholdings for that paycheck. We shouldn't have to manually do this though, Is there a way where the system will not try to take all of the additional withholdings when the employee doesn't have enough money to do so? Or at least give us a warning/error out like it does when they are going to have a negative check because of retros and not having enough funds?
