Why does the number of days displayed on an employee's Leave Application screen differ from the actual number of days applied for?

The number of days on an employee's Leave Application screen may differ from the actual number of days applied for because:
  1. the leave application was submitted for the incorrect number of days,
  2. the incorrect working days have been selected on the employee's Pay Rate Details screen, which allows the system to include them when calculating the number of days applied.
                  Navigate > Employee > Pay Rate Details > Additional

                  
  1. there was a public holiday in the period that was applied for. Verify if the affected leave type was configured to include public holidays when calculating the number of days for leave applications.
