InfoPath Dev

Hi,

I have two lists "Parent" and "Child. The list has one parent - many child item relationship.
I need to provide data for both parent list item and corresponding child list item using infopath form.
I am able to add item to the parent list using infopath.But not to child list.
In Infopath 2010, I was able to achieve the above using repeating section and custom code.
Now I need to achieve the same for SharePoint online, without custom code.
How to add item to child list on submitting parent details?

Thanks in advance,

 If you can't use code, you can use CAML. Here's a pretty long thread on this: http://www.infopathdev.com/forums/t/26246.aspx?PageIndex=1
