Salesforce Field Service Mobile App: "An Error Has Occurred. Try Again." When Scanning Pending Product Transfer Request from Inventory Tab — Serialized Product Sharing Settings Set to Private

The error occurs because the Salesforce Field Service mobile app cannot access Serialized Product records during the product transfer scan. This is a permissions issue.

Option 1: Update Sharing Settings on the Serialized Product Object (Recommended for Community Users)

1. Go to Setup > Sharing Settings.
2. Find Serialized Product in the object list.
3. Change the Default Internal Access (and Default External Access if applicable) from Private to Public Read/Write.
4. Click Save.

After this change, community users can access the Serialized Product records required for the product transfer scan.

Option 2: Grant Explicit Object Permissions via Permission Set (For Internal Users or When Sharing Settings Cannot Be Changed)

1. Go to Setup > Permission Sets.
2. Open the permission set assigned to the affected user.
3. Go to Object Settings > Serialized Product.
4. Enable the following permissions: Create, Read, Edit, View All Records, Modify All Records.
5. Click Save.

Note: Option 1 (Sharing Settings change) is most effective for community-licensed users. If the error is occurring for internal Salesforce users as well, Option 2 (permission set with explicit object access) is recommended.
