Setting Up Deductions in HRMS and testing of set ups

This is a minor question, but with amount of work involved its worth some feed back.

Our benefit department is continually adding new deduction codes for replacement of old, seperation of group coding as well as new.  They have also set up these codes in the test environment, ran the payrolls for the testing.  As soon as testing was done these new codes were handed off to payroll to enter into production environment.

Within the last 6 months, benefits has decided they no longer will be setting up these codes in either test environment nor do anymore testing.  Testing is under the payroll department and all testing and set up should be done by payroll.
