The Timesheet Smoothing Process Workflow kicks-off when an individual timesheet is Submitted.  It splits each transaction on the timesheet when total timesheet actuals exceed total weekly availability for the resource.  Total weekly availability is determined by multiplying resource availability rate by the number of workdays in the week.  Non-workdays include weekends, holidays, PTO, and other scheduled days off, as set on the resource calendar.  If timesheet actuals <= total weekly availability, then the timesheet remains unchanged.  But if timesheet actuals > total weekly availability, then the following occurs. Each timesheet transaction is reduced by a calculated percentage that will reduce the total regular hours to equal the total weekly availability.  Then the remaining transaction hours are placed in a “Split” row for that task on that day, with an Input Type Code set based on a process parameter (which parameter can be set within the script action on the process). Note:  If a single day has overtime hours, but the total timesheet actuals <= total weekly availability, no splitting occurs.

This allows users without admin access to see the timeslice settings and also allows the data to be exported to excel easily.  Many organizations like to document their timeslice settings which is a manual process as you cannot export the timeslice page to excel.  This allows them to periodically export the portlet results to excel to meet their documentation requirements.
