Hi RobMCM,
It's a bit of a work around, but ...
The bulk of my employees are casual and paid per Award rates by age.
I had, due to some calculation issue I can't remember, awhile ago (pre upgrade) stopped putting the hourly rate in the employee card file where it prompts you and instead created a pay item such as 'Casual Level 1 - 19 years' with a set hourly rate assigned to that pay item.
Then when entering the pays would enter the number of hours on the 'Casual Level 1 - 19 years' line and completely ignore the 'Base Hourly' line (so it would show as 0 hours at $0.00 ph).
In the upgrade, if you put $0.00 in the Hourly Rate line in your screenshot, it won't calculate the annual salary and you will be able to put 0 hours in a pay cycle.
This will also then show both Annual Salary and Hourly Rate as zero on the top of the payslip, which is yet another reason the new payslips look terrible, but on a positive it isn't confusing any of my teenage staff with thinking they get a salary.
