Service Appointment Fields Unavailable in Service Resource Related List Configuration

Publish Date: Jun 12, 2026
Description
Problem

When configuring the Service Appointment related list on a Service Resource record page, fields such as Subject, Parent Record, Scheduled Start Date, and Scheduled End Date do not appear in the Available Fields picker. Although the related list is labeled "Service Appointments," only a subset of fields are available for configuration.
Cause

The Service Appointment related list on the Service Resource record page is backed by the AssignedResource object — the junction object that links Service Resources to Service Appointments. Only AssignedResource fields are exposed in the field picker. Fields such as Subject, Parent Record, Scheduled Start Date, and Scheduled End Date exist on the ServiceAppointment object and are therefore not available. This behavior is by design and reflects the underlying data model.
Resolution
Resolution

Because the standard related list is backed by AssignedResource, a Dynamic Related List component paired with a custom lookup field is required to surface ServiceAppointment-specific fields. Follow the steps below to resolve:

  1. In Object Manager, open the ServiceAppointment object.
  2. Create a new custom lookup field pointing to Service Resource (e.g., "Service Resource Lookup").
  3. Open the Service Resource Lightning record page in Lightning App Builder.
  4. Add a Dynamic Related List - Single component to the page.
  5. Configure the component to use the custom lookup field created in Step 2.
  6. In the field picker, select the ServiceAppointment fields to display (e.g., Subject, Parent Record, Scheduled Start Date, Scheduled End Date).
  7. Save and activate the page.


NOTE: This workaround requires adding a custom lookup field to the ServiceAppointment object. If existing records need to reflect this relationship, data migration may be required.


NOTE: The Dynamic Related List - Single component displays fields from one related object at a time. Displaying AssignedResource and ServiceAppointment fields side by side in a single list may require a custom Lightning component or an alternative page layout strategy.
