Error adding employee into payroll

I am receiving the following error when adding an employee into payroll:

Location/GroupBU restrictions exist which prevent adding this employee

• Enterprise ERP Payroll
• Payroll Processing
• Earnings and Deductions
• Generate Earnings and Deductions

• Location and Group/BU restrictions were defined on the generate screen which did not include the employee's Group/BU and Location codes.
• Employee Group fields were blank to blank instead of blank to ZZZZ

1. Access Generate Earnings and Deductions: Payroll > Payroll Processing > Generate Earnings and Deductions
2. Click Define, TAB into the Location From field, delete the current data to make the field blank
3. TAB into the To field and define ZZZZ to include all employees.
4. Repeat steps 2 and 3 for all ranges (Location From, Group/BU From and Employee Group) until all ranges are blank to ZZZZ
5. Click Accept
6. Re-open the Earnings and Deductions screen to add the employee(s) into the payroll.
