Thanks for the reply.

I can see how this can work, however it has it's limitations, in that I can't compare the job costs against the roster.

At one point, I did have the timesheet hours appear in the pay run, with a $0.00 value against them, and only the salaried amount being payable. But now, cannot find the setting, or combination of settings, to make this happen again.

Possibly another way for me to explain it, is a site supervisor, that is rostered to shifts, and attends site, but is on a fixed salary.  I need them to be an employee, and not another user in the system.
