I am trying to include overtime on the list of wage categories that are exempt from the calculation of annual and long service leave. When I select the overtime categories to be exempt in the relevant entitlement category and then select OK in the Entitlements Information window I get an error message saying that exemptions can only be applied to hourly wage categories. But overtime is an hourly wage category so I'm confused as to what I need to change for this to work. At the moment annual and long service leave is accruing on overtime hours which is clearly not right.
