Switching from One payroll Area to Three Payroll Area

Dear All,

In my client place client is coming up with two more payroll area requirement, earlier there was only one payroll area.

To do that the steps i need to follow is

Creating two payroll area, creating control record, assignment in ABKRS feature, assigned to it's date and period modifier.

Assigning the new payroll area to the employee with date 1st Apr. 2012.

Is anything more to check?

Thanks,

Santosh
