You use this function to define priorities between specific selection classes when a valuation model is evaluated. If periods from priority-relevant selection classes overlap, the SAP System evaluates the period with the highest priority.

The priority is relative. The priorities are only applicable between selection classes to which priorities have been assigned.

A selection class without a priority has the value 0. Periods for these selection classes are not included in the comparison and are transferred for evaluation irrespective of the other priorities.

To define a selection class priority for the evaluation of the valuation model, see Customizing for Personnel Administration under Evaluation Bases ® Calculation of Employment Period ® Valuation Model ® Define Valuation Model.

In Public Sector payroll for a country, the probationary period is extended due to sick leave. If the employee uses annual leave during this absence period, the probationary period is not extended. The Annual vacation absence has a higher priority here than the Illness absence. If the Annual leave absence overlaps with the Illness absence, only the Annual leave absence is counted. Other periods, for example, the period of active employment, or the capacity utilization level are not included in this comparison and are not given a priority (indicator 0).

The following graphic shows how priorities between overlapping periods are processed. If a priority was not assigned, the absence due to illness would affect the result since the weightings of 0 and 1 would be multiplied together.
