Whenever an appointment is populated with an end date, the system sets the salary to zero for the particular appointment. This is by design to prevent incorrect salary generation against ended appointments.
If the appointment was ended in error and the end date is removed from the appointment, the correct procedure to ensure the appointment gets paid against in the payroll run is to have a new salary added for the said appointment.
If this is the case, record a new salary amendment for the appointment and re-run the payroll jobs.
If the issue persists after entering the salary in the system, please raise a new case online, reference this article's title and include the following details:
