Technicians are used for:
- Assigning to Service Appointments individually or as part of a Crew
- Filtering available resources based on Territory and working hours
- Validating qualification requirements through Skills and Certifications

Part 3 – Assigning a Territory to a Technician
A Territory must be assigned to a Technician before they can participate in Service Appointments. Technicians are only visible in the assignment dropdown for Appointments that belong to their assigned Territory and fall within their active time period.
- A Technician can be assigned to one or more Territories
- Each Territory assignment can have its own separate working hours
Steps
- Go to the Technician's detail page.
- Navigate to the Territories tab.
- Click Assign Territory.

- Fill in the form:

Territory: Select the Territory where this Technician will operate
Start Date: The date the Technician begins operating in this Territory
End Date: The date the Technician stops operating. If left blank, the assignment is open-ended (no expiry). - Click Save.
Overlapping Time Period Warning
The system validates for overlapping date ranges when assigning Territories. If a Technician is already assigned to the same Territory with an overlapping date range, you will see:
"This territory already exists within an overlapping time period"

How to resolve: Adjust the Start Date or End Date so that the new assignment does not overlap with the existing one.
| Case | Territory | Start Date | End Date | Valid? |
| Existing | Territory A | 01/01/2026 | 31/01/2026 | — |
| ❌ Invalid | Territory A | 15/01/2026 | 15/02/2026 | Overlaps |
| ✅ Valid | Territory A | 01/02/2026 | 15/02/2026 | No overlap |
Part 4 – Viewing Assigned Appointments
The Appointments tab on the Technician's detail page displays a list of all Service Appointments the Technician is currently assigned to. This gives a quick overview of their active workload.
