Delete all child siblings when deleting a parent

[StephenSaid]

When I delete a parent from the TransferHeaders table, I was expecting that all the child items related to that parent gets deleted. They are not being deleted at the moment.

The following is how I have the Ref field in the child table: Transfers

Is it possible to have the child items automatically deleted when a parent item is deleted or should I mark the parent as deleted in a new field and then run a bot to delete both the children and the parent?
