This will most likely be caused by MicrOpay calculating the number of days in the application based on the current setup of public holidays or work patterns in MicrOpay. If changes were made after the leave had been applied for in ESS or another third-party system, the leave hours will differ from the expected ones.
The hours calculated for the period will depend on the number of days the original leave application was for and how many periods the leave falls over.
Below is an example of how the hours are calculated when a public holiday is entered after the Leave Application was submitted:
4 weeks (20 days) of leave paid at 8 hours per day equals 160 hours
A public holiday was entered in week 1, so the hours per day have been recalculated as 160/19 = 8.42
Week 1 will be 4 * 8.42 = 33.68
Week 2 will be 5 * 8.42 = 42.10
Below is an example of how the hours are calculated when a public holiday is removed after the Leave Application was submitted:
4 weeks (19 days leave plus 1 public holiday) of leave paid at 7.5 hours per day equals 142.5 hours (19 * 7.5)
A public holiday was removed in week 1, so the hours per day have been recalculated as 142.5/20 = 7.125
Week 1 will be 4 * 7.125 = 28.5
Week 2 will be 5 * 7.125 = 35.625
Note: The public holiday planner needs to be updated manually in MicrOpay and it is important to always keep this up to date. It is recommended that when you make changes to the Public Holiday Planner or Work Pattern that any affected Leave applications be cancelled and resubmitted.
