servicenow related list change not reflected unless list control table config updated

 https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB1296669

Creating a sys_ui_related_list_entry does not reflect on the form's related lists unless the config related list/ list control is updated.

Steps to Reproduce

1. Hop into any Tokyo instance
2. Open any incident record and check the number of related lists present on the form
3. Navigate to the default view of the related list record for incident table from backend ( sys_ui_related.list )
4. Create a new related list entry ( ex : task_sla.task ) and Save
5. Now reload the incident that was opened earlier
6. The Related list is not reflected.

Workaround

This is expected behavior and by design in all currently supported releases.

To make the change appear, go to your table that you have newly added related list,  go to list layout, select your view, add or remove a column *****************  OR you can do that to the related list table, that would work too
