Once a job has been created by / through an order, it still must be scheduled or "activated".
This responsibility typically falls on the office or dispatch manager.
Go to Field Service --> Schedule Manager. You will see a new job under the date you set it for for the company to address. The tooltip can give you a quick glance at the jobs and orders/order types for that day:
This guide assumes that a Schedule and Rroute have already been created. see Managing Schedules
Click the blue route number to open up the Route List for the day
The Route List / Manager will open and you will see your previously created job in the Unassigned list.
Click the 3 dots and select Move to R{#} depending on how many Routes you have created for this day
The job will move to the selected route. Click Close
Congrats! Your job has now been scheduled!
