In addition to the regular hourly wage, you can also use other hourly wages. This page describes how to calculate hourly components versus another hourly wage.
In the Salary dashlet on the employee level, there are four other hourly wages to select, in addition to the normal hourly wage: two gross hourly wages and two net hourly wages. Hour components can subsequently be calculated based on these other other hourly wages.
In the hours model, you can indicate which type of hourly wage to use to calculate each hour component.
