I would try to follow some basic learning paths in the Academy like this one: https://academy.mendix.com/link/path/40/Mendix-Basics .

You could show a grid of Invoices. Below the grid you can have a dataview that lsitens to the grid above. In this dataview you can then put a grid with the invoice lines that you retrieve over the association. You will learn all this stuff in the basic course also on how to create new invoice lines etc.

Regards,

Ronald
