Assign a Permission Set

After creating your scratch org and deploying the source, you must sometimes give your users access to your application, especially if your app contains custom objects.
  1. If needed, create the permission set in the scratch org.
    1. Open the scratch org in your browser. 
      1sf org open --target-org <scratch org username/alias>
    2. From Setup, enter Perm in the Quick Find box, then select Permission Sets.
    3. Click New.
    4. Enter a descriptive label for the permission set, then click Save.
    5. Under Apps, click Assigned Apps | Edit.
    6. Under Available Apps, select your app, then click Add to move it to Enabled Apps.
    7. Click Save.
  2. Retrieve the permission set from the scratch org to your project. 
    1sf project retrieve start --target-org <scratch org username/alias>
  3. Assign the permission set to one or more users of the org that contains the app: 
    1sf org assign permset --name <permset_name> --target-org <username/alias>

    The target username must have permission to assign a permission set. Use the --on-behalf-of flag to assign a permission set to non-administrator users.

    1sf org assign permset --name <permset_name> --target-org <admin-user> --on-behalf-of <non-admin-user>
You can also assign permission set licenses to users using the org assign permsetlicense command. It works similarly to the org assign permset command.
