How to make child form "required"

Hi All,

I have a nested form. I am not being able to make the filling of the nested form as “required”.
I have tried making the virtual column that makes the child form appear in the parent form, as “required” but that didn’t work.
Even in the Order capture sample app if the order details are left empty, the parent form can still be saved.
Thanks in advance.

One workaround… choose another suitable column and write a validation like COUNT([Related Records])>0 with a suitable error message.
