The seniority calculation can be carried out in two ways in the SAP system, depending on whether or not you want to obtain a payroll with a list of the partial items corresponding to each payment time period.

If, in your company, you do not need to obtain a breakdown list of the amounts, you process the seniority calculation in the payroll through the function module ANTIG.

The ANTIG module is linked to the standard indirect valuation procedures of the basic pay wage types.

The function module ANTIG performs the following steps:

• processing of the infotype ’Seniority‘ (0092) to determine whether the employee is excluded from the seniority calculation (exemption indicator)

• if not, calculating cumulated time periods (automatic calculation) and/or annual periods (without automatic calculation).

• generating partial payment wage types corresponding to the different seniority time periods (two-year, three-year periods, etc.) necessary for payroll.

• valuating accrual wage types generated for calculating seniority

• adding the said wage types and returning the total seniority amount cumulated.

On triggering the payroll program, the WPBP function reads, among other data, the data of the infotype ‘Basic Pay’ (0008), within which seniority is included. The total seniority amount is calculated and included in the payroll process.
