When Flex Sync is not configured, the Axsy Field Service App will prime data using a default priming scope. 


1. The app has been given a default priming depth of 2. This means that from the Service Appointment (the root Object of the app's priming "graph"), we will prime the next layer based on the "Parent Record" field of the Service Appointment. This should be either a Work Order or Work Order Line Item.



2. Given that the depth is 2, the Related Lists of the Parent Record (e.g Work Order or Work Order Line Item) that are primed to the app are dependent on them being on the Page Layout of that Object. On the other hand, all fields and their Lookup details are primed to the app regardless of whether they are on the Page Layout of the Parent Object. Please see this Smart Forms article for more information on this: Priming mapped fields in the Axsy app


3. Flows that are primed to the app need to be in App Extensions under Field Service Mobile Settings (Salesforce Setup). 



4. Quick Actions that are primed to the app need to be added to a record's Page Layout.
