To create a seeding template for the purposes of seeding Salesforce Field Service objects, do the following:
In the Type field, select the Nodes option.
From the Create From field's drop-down menu, select the Field Service pre-defined template option.
Click Create. After some brief processing, the Template Builder tab opens displaying the newly created, Field Service seeding template. The template is in Edit mode.
Note: Because Field Service implementations can vary, if you receive a warning that there are missing objects, you can simply remove those objects from the template.
The Own authenticated user must have the Field Service Admin permission sets assigned, as well as appropriate system and app permissions for the seed to be successful.
