Why can't I create a new Service Appointment for a field agent with a partially completed appointment? How does an in-progress or incomplete appointment affect scheduling new appointments for the same field agent?
In Zoho FSM, if a field agent has a Partially completed or In-progress Service Appointment, the system may block scheduling a new one for them due to availability conflicts.
- A partially completed appointment means the Actual Start Date/Time is recorded, but the Actual End Date/Time is missing.
- This leaves the appointment in an ongoing state, and Zoho FSM treats the field agent as unavailable, regardless of the scheduled end time.
- Even if the new appointment is on a different day, the ongoing status causes a conflict.
- You may see the error: “Appointment Conflict with Ongoing Appointment.”
To resolve it:
- Option 1 – Complete the previous appointment:
- Ask the field agent to mark the appointment as Completed or enter the Actual End Date/Time.
- Option 2 – Enable Allow overlapping appointments:
To enable overlapping appointments in Zoho FSM:
- Go to Setup > Field Service Settings > Transaction Settings.
- Scroll to the Appointment Scheduling Preferences.
- Enable the toggle for Allow Overlapping Appointments.
- Choose one of the following options based on your preference:
- Allow Overlapping without Warning: Appointments can be scheduled without any warning, even if they overlap.
- Allow Overlapping with Warning: The system shows a warning with the list of conflicting appointments, but still allows the scheduling.

Also enable overlapping timesheets (if needed) :
Enabling Overlapping timesheets allows field agents to track multiple jobs at once or multitask across appointments
- Navigate to Setup > Field Service Settings > Transaction Settings
- Under Time Sheet Settings, enable Allow Overlapping or Concurrent Timesheet Entries

This lets you schedule a new appointment even when the field agent has an appointment still marked as ongoing.
