TIMESHEETS & PAYROLL

Hi

In the past I have run my pays using the "normal" payroll procedure and for casuals and P/Ts and F/Ts, I have just put in their total hours for the fortnight - eg. 30hr ord hours, 10 hrs Sat, etc.  These were all costed to the same job.

I now have the situation where some of my casuals' hours will need to be costed to Job A and some of their hours will need to be costed to Job B.

What is the best way to do this?  Will I have to run two separate payrolls: 

1. The one I normally do using the "normal" payroll procedure; and 

2.  Then do a separate "timesheet payroll" for those casuals with hours split between two jobs?

Can you please explain the best way.  I have never done a payroll using timesheets, so if I have to do it that way for the split job casuals, can you explain that for me too.

Thanks
