Payroll Deduction

The PR05 has effective dates on the More tab that can be used to indicate the effective dates of the deductions.

I should add that the start and end dates will control whether or not the deduction is processed during payroll. It does not prevent a user from adding the deduction to an employee via PR14. If the deduction has a end date, the deduction will still be added to the employee but will reflect the end date that is entered on PR05.

I am wondering if someone knows how to set up a Union deduction that uses the following formula for example: 2.5 x the hourly rate of the employee only when this one works. I am having trouble to get the PR05 to point at the hourly rate of the employee. I can set up a custom calculation but I am trying to see if there is another way to set this up

Thanks,
