Before payroll could be run for an employee, the control record on this payroll area need to be released. This include if you are doing inhouse SAP Payroll or outsourcing payroll through an outside vendor, but utilizes SAP PCL cluster to track payroll run and extraction handle via PU12.
The payroll control record could be view via transaction code PA03 or via table T569V. On the payroll control record, it set the date retro date you can make modification to an employee that impact payroll and what payroll period you are currently in or going to be extracting for. When the payroll is in "released payroll" status, this mean it is ready for payroll extraction to occur for that payroll period. Once extraction is completed, the payroll is in exit payroll status to collect changes for next payroll period.
You could find out more about payroll through this really neat book I got recently.
