When you log in to the Axsy app it syncs specific data, making it available for offline use. The app primes (syncs) all Fields and Related Lists within the configured syncing scope, however, Related Lists need to be on the Page Layout of the record's Object Type in order to synced.
Despite all Fields of the record running the Form being synced to the app, it is best practice to also add Fields you want to view on the Axsy Mobile App to the Page Layout so that they will be displayed in the Details tab of the app.
Add Fields to the Page Layout of an Object
To ensure that the values of elements you have created mappings for will be displayed in the Axsy app, navigate to Setup > Object Manager in Salesforce and then to the Page Layout of an Object within the syncing scope.
The Operating Hours field for Account is synced to the app, however, to ensure that it gets displayed in the Axsy app as a mapped value, it has been added to the Page Layout for Account.
Add Related Lists to the Page Layout of an Object
To ensure that the Related Lists you have created mappings for are being primed to the app, navigate to Setup > Object Manager on Salesforce and then to the Page Layout of the Object within the syncing scope. In this case, the Object is Work Order. Drag and drop a Related List into the corresponding section.
Here, Products Consumed has been added to the Related Lists section of the Page Layout in order to map Products Consumed to an element in a Smart Form.
If you try and run the app with mappings to Related Lists that are not a part of the Page Layout, an error will prevent all Related List mappings from functioning.
