My question if I want to pull a lot of information about Supplier is should my portal in the Products record be from Suppliers or from Lines? If the best answer is Lines, could I still have a count of related Suppliers by using the primary key from that table in the portal? Is it a bad idea to use fields from a related tables portal other than its own? Thanks
I'd show a portal of Lines on Products, and then show fields from Suppliers, and a count of Suppliers. This will allow you to add (and show) additional attributes of Lines (full line? partial line? only under certain conditions? From and to dates?) in your portal. You can also more easily spot of you accidentally end up with a second line. Lastly, this gives a handy place for the user to select a supplier on a line.
You can use fields from tables other than the portal's focus, so long as they are "beyond" the portal focus.
Thanks for the insight, thing are working well with the setup.
