In this step, you decide which absence valuation rules should be paid according to the "as if" principle.
The "as if" principle of absence valuation means paying employees exactly as if they had worked. This includes bonuses that form part of the employee's planned working time. Overtime is not taken into account when absences are valuated using the "as if" principle.
Absence valuation based on the "as-if" principle can be effected
in time wage type selection in time evaluation. In this case, wage
types that have already been determined for absence valution are
passed on to Payroll Accounting via table ZL. These wage types are
assigned the IFTYP A in time evaluation, on the basis of which you
can query the absences.
When absences are valuated in Payroll Accounting, these absences are only taken into account if you have specified additional regulations (regarding the formation of counting classes, for example).
An employee grouping is paid according to time worked. One employee should have worked 160 hours in the month. Instead, he worked 120 hours and was unable to work the other 40.
The standard SAP delivery contains sample entries for absence valuation.
