Related list missing from form: expected related list not visible

Access Control Lists (ACLs) are blocking read access to the related table or specific fields within the related list. (high likelihood)

The related list was removed from the form layout for the specific view or user role accessing the form. (high likelihood)

The table relationship definition is inactive or incorrectly configured in the Dictionary Entry or Reference field setup. (medium likelihood)

User interface policies or client scripts are dynamically hiding the related list based on form conditions or field values. (medium likelihood)

The related list configuration has an invalid filter condition or query that returns no results and causes display issues. (low likelihood)

Step 1: Navigate to the affected form and right-click to select Configure > Form Layout to verify the related list is present in the form configuration.

Step 2: Check System Definition > Tables & Columns and verify the relationship field exists and is active between the parent and child tables.

Step 3: Go to System Security > Access Controls (ACL) and search for ACLs on the related table to ensure the current user has read access.

Step 4: Test with an admin account to determine if the issue is role-based, then review the user's roles and group memberships in User Administration.

Step 5: Examine any UI Policies under System UI > UI Policies that might be hiding the related list based on form field conditions.

Step 6: Review client scripts and business rules that might be manipulating the form's related lists using g_form.removeOption or similar methods.

Step 7: Check the related list configuration by navigating to the form, right-clicking the related list area, and selecting Configure to verify filter conditions.

Step 8: Clear browser cache and test in an incognito window to rule out client-side caching issues affecting form rendering.
