How do I configure the system so that employees can specify the time of day when applying for leave for a fraction of a day?

This feature is available on all Deel Local Payroll powered by payspace payroll editions
To allow employees to specify the time of day they will be on leave, enable the "When applying for leave of less than 1 day, show an indicator for the employee to select whether the leave is taken in the morning or the afternoon" checkbox under the Employee self service section on the Leave Settings screen.
Navigate > Configuration > Human Resources > Leave Administration > Leave Settings > Employee self service
When enabled, a new field will appear when applying for leave and changing the number of days to less than a day. The option selected here will also show in the workflow for the approvers to see.
Navigate > Employee > Leave > Application
