By default, whatever you set as an employee’s regular pay will use the system pay code BASIC.
You may want to change this for some employees, perhaps to differentiate between pay to employees and pay to directors, or to analyse pay by departments.
Before you can change the code used, you need to create a new code that is suitable.
Create a new Pay Code and ensure you set it as an Addition code and the calculation method is Fixed Amount.
Now that you have created a suitable code, a new option will appear when you edit the employees pay options.
The option Pay Code defaults to BASIC.
You can now change update this option and select the new code you just created instead.
Remember that setting the employee defaults only affects future payruns.
If you have a payrun already open, you need to edit the regular pay on the payrun to change the code there too.
