Valuation of Primary Wage Types 
Use
To valuate primary wage types using the principle of averages, you must flag these wage types accordingly. To do this, use the Processing Classes, Cumulations, and Evaluation Classes view 8V_512W_D) to enter a specification for primary wage type in processing class 15. Each specification of processing class 15 corresponds to a calculation rule in the Calculation Rules for Averages view (V_T511A).
The following parameters must be set for each calculation rule:
The Averages view (V_512W_C) enables you to determine the secondary wage type for average bases in which the primary wage type for the calculation of averages is cumulated. It also enables you to determine whether the RTE (Rate), NUM (Number) or AMT (Amount) field is cumulated.
