Modifying the Variable SDI Process

Global Payroll for Mexico delivers a process list (CALC SDI VARIAB) for calculating variable SDI. If you need to add earnings that contribute to the variable SDI amount, follow the procedure below.

To include an earnings in the Variable SDI process:

1. Select the earning that is a member of the SDI bimonthly accumulator.

   This is very important. If the bimonthly accumulator does not exist for the earning, you must create a new one. Select the earning and the corresponding accumulator on the Variable SDI page.

2. Select one of the three formulas (integration methods): IM FM 100% VAR, IM FM TOP VAL IMSS, or IM FM PREMIO INT on the Variable SDI page.

All earnings belong to one of the three formulas (integration methods). Below are some examples:

Earning	Formula
BONO	IM FM 100% VAR
VALES DESPENSA	IM FM TOP VAL IMSS
COMISIONES	IM FM 100% VAR
PREMIO DE ASIST	IM FM PREMIO INT

Note:

Do not add the earnings elements to the SDI VARIABLE section.

The order in which you run the SDI FIJO (Process SDI MEX) and SDI VARIABLE processes is very important because the fixed process (SDI FIJO) depends on the variable process (SDI VARIABLE). For example, the date for the SDI FIJO corresponds to a hiring or salary increase date for the payee and the SDI VARIABLE as defined by law is the first day of each two months based on the earnings of the previous two months.
