Additional payments constitute additional wage elements which are not usually accounted for in every payroll period. Unlike the Infotype Recurring payments and deductions, however, they do not occur at a particular frequency. Instead, they are accounted for only once on a fixed date, which you determine when you create an additional payment.
In Japan, additional payments include the following:
SYOYO, Non-Periodical SYOYO, and retirement allowances are processed by the Off-cycle payroll process.
You can create additional payments in Infotype 0015 and then change them using infotype maintenance.
Unlike basic pay, additional payments can have a different account assignment. For example, you can define a cost center instead of the master cost center to deal with costs that arise as a result of these payments.
