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?

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.
  1. A partially completed appointment means the Actual Start Date/Time is recorded, but the Actual End Date/Time is missing.
  2. This leaves the appointment in an ongoing state, and Zoho FSM treats the field agent as unavailable, regardless of the scheduled end time.
  3. Even if the new appointment is on a different day, the ongoing status causes a conflict.
  4. You may see the error: “Appointment Conflict with Ongoing Appointment.”
To resolve it:
  1. Option 1 – Complete the previous appointment:
    1. Ask the field agent to mark the appointment as Completed or enter the Actual End Date/Time.
  2. Option 2 – Enable Allow overlapping appointments:
            ​To enable overlapping appointments in Zoho FSM:
    1. Go to Setup > Field Service Settings > Transaction Settings.
    2. Scroll to the Appointment Scheduling Preferences.
    3. Enable the toggle for Allow Overlapping Appointments.
    4. Choose one of the following options based on your preference:
      1. Allow Overlapping without Warning: Appointments can be scheduled without any warning, even if they overlap.
      2. 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
    1. Navigate to Setup > Field Service Settings > Transaction Settings
    2. 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.
