Long Service Leave - Hourly v Salary

Hi,

I've got employees paid both Hourly and Salary.  

I've recently setup LSL and am having trouble getting the Salary staff to accrue.  I have entered the existing LSL balances for all staff.

I have setup ONE Wages category for Long Service Leave.  "Hourly" selected per the Help instructions.

I have TWO Entitlement Categories, one for Hourly staff and one for Salary staff.  Followed the Help instructions on how to set this up. 

I have run a payroll and the Hourly staff appear to have accrued LSL as they should, but the Salary staff haven't accrued anything and still show the opening balances I entered.

Do I have to setup a second Wages category for the Salary Staff?

Any other suggestions or things to check?

cheers

Lisa
