I have recently received a "private message" asking me for documents regarding SAP's Best Practices regarding Payroll.
I did reply to the sender, inviting him/her to do a simple Google search using "sap payroll best practices" as the search element, and one of the suggested sites appeared to be very interresting, and I wanted to share it with everyone.
