How to prevent save if no data in detail screen

[James_McFarlane]

Hi I have an order app with a header screen and a detail screen. I would like to prevent save in the header screen if no items where introduced in the detail screen.

Thanks,

What do you mean by “header screen”?

[James_McFarlane]

Wrong wording. I the first screen is for customer name, order date, delivery address, general order information.

Here is a screen shot to help clarify.

You can simply make “Platos/Bebidas” required.

That was the trick. Thanks!
