How do I get all chld records from a parent record in SS?

I think if they are attached as sublist you can access them, try doing &xml=T in url, but if not I'll suggest to run a search on child record and put in filter Parent is ABC

So the child records are not a sublist they are just parked as child record and appear under "Child Records" tab. since there is no sublist id you're saying I have to use a search to pull them?

Can you share a screenshot of the list of the child records? There probably IS a sublist ID.
