***************
saving plan payroll process is the same as any other plan.
wage types as per standard will be assigned in the benefits integration in payroll.
you will assign the combined contributions limit in table V_T74FW and whether it is a pre tax or post tax in table T5UCA.
you can have any number of 401K plans according to the vendor. an employee can be assigned to multiple plans at the same time, but combined contribution limit will check and will not allow the contribution beyond the limit mentioned in the table.
employees above 50yrs of age are eligible for additional contribution, which is $5500 from jan 2009, this limit needs to be fixed in table V_T7USBEN03
