In SAP Payroll the delivered variable type KAU (table T511V) is defined as “partial-period factor in work days incl. unpaid absences for all counting classes.” When you assign KAU to a wage-type valuation rule or PCR, the system determines the divisor (planned work days) and the numerator (paid work days) after first subtracting any unpaid absences, so the factor already reflects absence reduction across every counting class. Therefore it is the required variable whenever the factor must be based on work days and must always reduce for unpaid absences, irrespective of the absence counting class.

A. SAP02 Calculates factor in work days but ignores unpaid absences; therefore does not fulfil the requirement.

C. AAU Calculates factor in work hours, not work days; wrong time unit for the scenario.

D. SAP Placeholder for individual SAP0x variables; none of them include unpaid absences in work days for all counting classes.
