Maybe you can try adding a pre-insert trigger on your master block to check if data exist in the detail block.

A simple way of doing that is to check whether a required item in the detail block has a value.

Something like

if :detail_block.id is not null then
   -- everything is OK, there is at least one record in the detail block
   null;
else
   message('No records in detail block');
   raise form_application_error;
end if;

Otherwise, you'd need to scroll through the whole detail block and count records (not necessarily one by one - LAST_RECORD would do the job).

Except you can't do that from pre-insert.
