To solve this:
Check Service Management
Go to Locations
Click Locations Customers
Click Main Customer Details
Go to Primary Customer denotes the main customer account at the location
If multiple customers are linked to the location, the Primary customer should automatically populate when creating a service order for that location.
Ensure the Time Zone is set on the Location Details Main page. A missing time zone configuration can prevent the Primary customer from defaulting correctly.
Notes:
Verify that only one customer is marked as Primary for the location.
After updating the time zone, add a new service order.
