Salesforce Education Cloud: Standard Object Not Available as a Related List on Lightning Pages

The Lightning App Builder's Related List components dynamically query the parent object's standard page layouts to determine which related child lists are available to display. If a child object is missing from the Lightning App Builder picker, it must first be exposed on the classic page layout.

Work through the following steps to resolve this behavior:

Cause 1: The related list is missing from the parent's classic page layout

Root Cause: Lightning App Builder reads the master metadata schema from the Classic Page Layout engine. If the child related list has not been dragged onto the classic page layout assigned to your profile, the App Builder's component properties pane will hide it.

Step-by-Step Fix:

1. Navigate to Setup > Object Manager.

2. Open the PARENT object that hosts the record page you are trying to edit:

   • Example 1: Program Term Application Timeline (API: ProgramTermApplicationTimeline)

   • Example 2: Account (API: Account)

3. On the left sidebar, click Page Layouts and open the specific page layout assigned to your user profile.

4. In the upper palette, click Related Lists.

5. Drag the CHILD related list from the palette down into the Related Lists section of the page layout:

   • Example 1: Drag Education Institutional Offerings onto the Program Term Application Timeline page layout.

   • Example 2: Drag Individual Applications onto the Account page layout.

6. Click Save. If prompted with "Overwrite users' related list customizations?", click Yes to apply the layout globally.

Cause 2: The Child Relationship Name is undefined or unindexed

Root Cause: If the classic page layout has been saved but the Related List component still does not offer the child object, the relationship name may be missing from the lookup field metadata.

Step-by-Step Fix:

1. Go to Setup > Object Manager and select the CHILD object (e.g., Education Institutional Offering or Individual Application).

2. Click Fields & Relationships and select the lookup field pointing to the parent object.

3. Verify that the Data Type is indeed Lookup Relationship and that the Related To property points to your target Parent Object.

4. Check the Child Relationship Name field. If this value is blank, click Edit, define a clear API relationship name (e.g., EducationInstitutionalOfferings), and save.

5. Go back to Setup > Lightning App Builder and open your parent record page.

6. Search for the Related List - Single component on the left-side standard components pane and drag it onto your canvas.

7. In the property editor on the right, select your child object from the Related List dropdown menu.

8. Click Save, then click Activate to deploy the updated page to your profiles.

Validation

1. Navigate to your app in Education Cloud and open a parent record (such as a specific Program Term Application Timeline record).

2. Confirm that the child related list (such as Education Institutional Offerings) now appears on the page.

3. Create a test child record under this parent to ensure that the related list populates and displays the records correctly.
