With tax reforms effective December 20, 2001, the Variable SDI process is now run bimonthly instead of monthly. In order to accommodate this legislative change, you will:
Indicate the method for calculating the variable SDI on the Base Days for Variable SDI field on the General Parameters page.
Choices are 60 Days, Bimonth Days, Hourly Payee, or Paid Days.
Define variable SDI parameters for a pay group on the Variable SDI page.
(Optional) Insert calendars on the SDI Calendars page to specify the month to which each weekly or biweekly calendar accumulates.
Run the Variable SDI process on the Calculate Absence and Payroll page.
You must create a bimonthly calendar and execute the CALC SDI VARIAB process list.
Use the Variable SDI page (GPMX_VAR_SDI_PARM) to select the earnings, accumulators, and formulas used in the Variable SDI process for a pay group.
