hi
you can try something like this:
select *
from sales_order.tbl_line_item
where sales_order.tbl_line_item.item_id='PSNC' and
sales_order.tbl_line_item.so_number not in (
select sales_order.tbl_item_bom.so_number
from sales_order.tbl_item_bom
where sales_order.tbl_item_bom.item_id != 'TMPSN');
hope it helps,
christoph
