Under Reporting in the 5-3-1 Payroll Calculations window, there are four text boxes in which you may have to enter values. Two of them are Union and Benefit:
Union: You can assign a calculation to a specific union. When you print a union report, Sage 100 Contractor includes the payroll calculation totals assigned to the union.
Benefit: You can select the type of benefit for which the calculation is used. When you print certified payroll reports, Sage 100 Contractor includes the payroll calculation totals for the benefit.
