This message relates to the automatic reduction of Normal hours when leave hours are entered on a timesheet. This is a setting that can be applied to Normal and leave income codes.
To set this up for the Normal income types:
Go to Setups, Payroll, Income Types, Income Types, Maintain.
Select the Normal hours income code and tick to Reduce Hours with Leave.
Accept (F9) to save the changes.
For leave codes i.e. Annual and Sick (Personal) leave:
Go to Setups, Payroll, Income Types, Income Types, Maintain.
Select the leave income codes individually and tick Reduce Normal Hours.
Accept (F9) to save the changes.
If the leave hours entered on the timesheet are less than then Normal hours, then they reduce accordingly so you don’t have to manually adjust them down. However, if the leave hours entered are greater than the Normal hours then the above message appears stating this. The normal hours can't be reduced because they are less than leave hours entered. The automatic reduction won't happen in this instance, and the user will need to manually remove the Normal hours or reduce it to zero.
