sage payroll

Hi, i have just started working for a company about a week back. One of the employee is pregnant. She is going on maternity leave from 01/04/12. Her baby is due on 13/04/12. From 01/01/12, the company has set up all the new cost centres & all the employees have been given P45s & will be transferred to this new cost centre(service company) from 01/01/12. This employe is working for the company for past 6 years. so she is entitled to the full smp benefits. However will sage payroll calculate her correct smp & the correct amount recoverable from HMRC, as this new cost centre will have all the details from begining of this year.
