In Payroll, the Pay Run Management tab is where you can view and filter lists of pay runs from which to select and load a specific pay run to work in.
Note: The Data Entry and Pay Run Management tabs share the Quick Entry, Checks, Adjustments, and Time Data sub-tabs, which have the same functionality between Pay Run Management and Data Entry. The only difference is that, in Data Entry, you can simultaneously work with entries for multiple pay runs.
