Calculation of Seniority in the payroll 
In the SAP R/3 System, you carry out the seniority calculation within the payroll process frame for a specific payroll period.
Seniority is calculated through accruement methods, valuation methods and a calculation procedure that unites both methods in the
Infotype Seniority (0092).The payment method is the method used for establishing the seniority time periods to be taken into account in seniority calculation, such as two year periods, three year periods, etc., as well as the way in which the system uses them in the seniority calculation. The valuation method is the method that assigns a value or amount to the established time periods.
The correct seniority processing in the payroll process is connected with the system check of data entered in the infotype 'Seniority' (0092).
When processing data for calculating seniority in the payroll, there are two different procedures depending on whether or not your company requires the breakdown of those partial items that form the total seniority amount that will flow into the payroll:
infotype 'Basic Pay' (0008). The total amount of seniority is included in the said infotype through a seniority wage type The total amount appears as related to seniority in the employee payroll.
