Note: This release is in preview. Features described here don’t become generally available until the latest general availability date that Salesforce announces for this release. Before then, and where features are noted as beta, pilot, or developer preview, we can’t guarantee general availability within any particular time frame or at all. Make your purchase decisions only on the basis of generally available products and features.

Field Service Org Setup

Create a permission set with the Lightning SDK for Field Service Mobile permission, and assign this permission set to users who develop for or use Lightning web components in the mobile app.

This step is required for Field Service orgs. If you’re using LWC Offline in the Salesforce mobile app, skip to the next step.

Note

Lightning web components for LWC Offline-enabled mobile apps is an opt-in feature. To enable it for your org, you must create and assign a permission set for your mobile users that includes enabling the Lightning SDK for Field Service Mobile permission. This permission set is required to access and run LWCs within the Field Service mobile app. (While not technically required to develop LWCs, you’ll have a hard time developing components when you can’t run them.)

You can use this one permission set for any number of Lightning web components and mobile users.

Define a Permission Set for Your Org

Create a permission set that applies the permissions required to enable Lightning web components to users with the permission set.
  1. From Setup, enter Permission Sets in the Quick Find Box and select Permission Sets.
  2. Click New.
    • For Label, enter Field Service - LWC Offline.
    • For Description, enter Assign to Field Service Mobile users to give them permission to run LWC actions.
    • For License, select Field Service Mobile.
  3. Click Save.
  4. In the Find Settings box, enter Lightning SDK for Field Service Mobile and click it.
  5. Click Edit.
  6. Select the Lightning SDK for Field Service Mobile checkbox.
  7. Click Save.

Assign the Permission Set to a Mobile User

Assign the permission set that enables Lightning web components to users who must use or develop LWCs.
  1. From Setup, enter Permission Sets in the Quick Find Box and select Permission Sets.
  2. Select Field Service - LWC Offline, which is the new permission set.
  3. Click Manage Assignments.
  4. Click Add Assignments.
  5. Select your mobile user’s checkbox.
    For this quick start, the mobile user is you.
  6. Click Assign.
